DATAMONGO-1304 - After release cleanups.

UpdateMapper.getMappedObjectForField(…) invokes the very same method of the super class but handed in an already mapped value so that value conversion was invoked twice.

This was especially problematic in cases a dedicated converter had been registered for an object that is already a Mongo-storable one (e.g. an enum-to-string converter and back) without indicating which of the tow converter is the reading or the writing one. This basically caused the source value converted back and forth during the update mapping creating the impression the value wasn't converted at all.

This is now fixed by removing the superfluous mapping.

-== Running CI tasks locally
-
-Since this pipeline is purely Docker-based, it's easy to:
-
-* Debug what went wrong on your local machine.
-* Test out a a tweak to your test routine before sending it out.
-* Experiment against a new image before submitting your pull request.
-
-All of these use cases are great reasons to essentially run what the CI server does on your local machine.
-
-IMPORTANT: To do this you must have Docker installed on your machine.
-
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-openjdk8-with-mongodb-4.0:latest /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
-+
-2. `cd spring-data-mongodb-github`
-+
-Next, run the tests from inside the container:
-+
-3. `./mvnw clean dependency:list test -Dsort -Dbundlor.enabled=false -B` (or with whatever profile you need to test out)
-
-Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
-
-If you need to package things up, do this:
-
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-openjdk8-with-mongodb-4.0:latest /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
-+
-2. `cd spring-data-mongodb-github`
-+
-Next, package things from inside the container doing this:
-+
-3. `./mvnw clean dependency:list package -Dsort -Dbundlor.enabled=false -B`
-
-NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

-
-[[building-from-source]]
-== Building from Source
-
-You do not need to build from source to use Spring Data. Binaries are available in https://repo.spring.io[repo.spring.io]
-and accessible from Maven using the Maven configuration noted <<maven-configuration,above>>.
-
-NOTE: Configuration for Gradle is similar to Maven.
-
-The best way to get started is by creating a Spring Boot project using MongoDB on https://start.spring.io[start.spring.io].
-Follow this https://start.spring.io/#type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb[link]
-to build an imperative application and this https://start.spring.io/#type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb-reactive[link]
-to build a reactive one.
-
-However, if you want to try out the latest and greatest, Spring Data MongoDB can be easily built with the https://github.com/takari/maven-wrapper[Maven wrapper]
-and minimally, JDK 17 (https://www.oracle.com/java/technologies/downloads/[JDK downloads]).
-
-In order to build Spring Data MongoDB, you will need to https://www.mongodb.com/try/download/community[download]
-and https://docs.mongodb.com/manual/installation/[install a MongoDB distribution].
-
-Once you have installed MongoDB, you need to start a MongoDB server. It is convenient to set an environment variable to
-your MongoDB installation directory (e.g. `MONGODB_HOME`).
-
-To run the full test suite, a https://docs.mongodb.com/manual/tutorial/deploy-replica-set/[MongoDB Replica Set]
-is required.
-
-To run the MongoDB server enter the following command from a command-line:
-
-[source,bash]
-----
-$ $MONGODB_HOME/bin/mongod --dbpath $MONGODB_HOME/runtime/data --ipv6 --port 27017 --replSet rs0
-...
-"msg":"Successfully connected to host"
-----
-
-Once the MongoDB server starts up, you should see the message (`msg`), "_Successfully connected to host_".
-
-Notice the `--dbpath` option to the `mongod` command. You can set this to anything you like, but in this case, we set
-the absolute path to a sub-directory (`runtime/data/`) under the MongoDB installation directory (in `$MONGODB_HOME`).
-
-You need to initialize the MongoDB replica set only once on the first time the MongoDB server is started.
-To initialize the replica set, start a mongo client:
-
-[source,bash]
-----
-$ $MONGODB_HOME/bin/mongo
-MongoDB server version: 6.0.0
-...
-----
-
-Then enter the following command:
-
-[source,bash]
-----
-mongo> rs.initiate({ _id: 'rs0', members: [ { _id: 0, host: '127.0.0.1:27017' } ] })
-----
-
-Finally, on UNIX-based system (for example, Linux or Mac OS X) you may need to adjust the `ulimit`.
-In case you need to, you can adjust the `ulimit` with the following command (32768 is just a recommendation):
-
-[source,bash]
-----
-$ ulimit -n 32768
-----
-
-You can use `ulimit -a` again to verify the `ulimit` for "_open files_" was set appropriately.
-
-Now you are ready to build Spring Data MongoDB. Simply enter the following `mvnw` (Maven Wrapper) command:
-
-[source,bash]
-----
- $ ./mvnw clean install
-----
-
-If you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.8.0 or above].
-
-_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular, please sign
-the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change._
-
-=== Building reference documentation
-
-Building the documentation builds also the project without running tests.
-
-[source,bash]
-----
- $ ./mvnw clean install -Pdistribute
-----
-
-The generated documentation is available from `target/site/reference/html/index.html`.

+# Spring Data MongoDB
+
+The primary goal of the [Spring Data](http://projects.spring.io/spring-data) project is to make it easier to build Spring-powered applications that use new data access technologies such as non-relational databases, map-reduce frameworks, and cloud based data services.
+
+The Spring Data MongoDB project aims to provide a familiar and consistent Spring-based programming model for new datastores while retaining store-specific features and capabilities. The Spring Data MongoDB project provides integration with the MongoDB document database. Key functional areas of Spring Data MongoDB are a POJO centric model for interacting with a MongoDB DBCollection and easily writing a repository style data access layer.
+
+## Getting Help
+
+For a comprehensive treatment of all the Spring Data MongoDB features, please refer to:
+
+* the [User Guide](http://docs.spring.io/spring-data/mongodb/docs/current/reference/html/)
+* the [JavaDocs](http://docs.spring.io/spring-data/mongodb/docs/current/api/) have extensive comments in them as well.
+* the home page of [Spring Data MongoDB](http://projects.spring.io/spring-data-mongodb) contains links to articles and other resources.
+* for more detailed questions, use [Spring Data Mongodb on Stackoverflow](http://stackoverflow.com/questions/tagged/spring-data-mongodb).
+
+If you are new to Spring as well as to Spring Data, look for information about [Spring projects](http://projects.spring.io/).
+
+
+## Quick Start
+
+### Maven configuration
+
+Add the Maven dependency:
+
+```xml
+<dependency>
+  <groupId>org.springframework.data</groupId>
+  <artifactId>spring-data-mongodb</artifactId>
+  <version>1.5.0.RELEASE</version>
+</dependency>
+```
+
+If you'd rather like the latest snapshots of the upcoming major version, use our Maven snapshot repository and declare the appropriate dependency version.
+
+```xml
+<dependency>
+  <groupId>org.springframework.data</groupId>
+  <artifactId>spring-data-mongodb</artifactId>
+  <version>1.6.0.BUILD-SNAPSHOT</version>
+</dependency>
+
+<repository>
+  <id>spring-libs-snapshot</id>
+  <name>Spring Snapshot Repository</name>
+  <url>http://repo.spring.io/libs-snapshot</url>
+</repository>
+```
+
+### MongoTemplate
+
+MongoTemplate is the central support class for Mongo database operations. It provides:
+
+* Basic POJO mapping support to and from BSON
+* Convenience methods to interact with the store (insert object, update objects) and MongoDB specific ones (geo-spatial operations, upserts, map-reduce etc.)
+* Connection affinity callback
+* Exception translation into Spring's [technology agnostic DAO exception hierarchy](http://docs.spring.io/spring/docs/current/spring-framework-reference/html/dao.html#dao-exceptions).
+
+### Spring Data repositories
+
+To simplify the creation of data repositories Spring Data MongoDB provides a generic repository programming model. It will automatically create a repository proxy for you that adds implementations of finder methods you specify on an interface.  
+
+For example, given a `Person` class with first and last name properties, a `PersonRepository` interface that can query for `Person` by last name and when the first name matches a like expression is shown below:
+
+```java
+public interface PersonRepository extends CrudRepository<Person, Long> {
+
+  List<Person> findByLastname(String lastname);
+
+  List<Person> findByFirstnameLike(String firstname);
+}
+```
+
+The queries issued on execution will be derived from the method name. Extending `CrudRepository` causes CRUD methods being pulled into the interface so that you can easily save and find single entities and collections of them.
+
+You can have Spring automatically create a proxy for the interface by using the following JavaConfig:
+
+```java
+@Configuration
+@EnableMongoRepositories
+class ApplicationConfig extends AbstractMongoConfiguration {
+
+  @Override
+  public Mongo mongo() throws Exception {
+    return new MongoClient();
+  }
+
+  @Override
+  protected String getDatabaseName() {
+    return "springdata";
+  }
+}
+```
+
+This sets up a connection to a local MongoDB instance and enables the detection of Spring Data repositories (through `@EnableMongoRepositories`). The same configuration would look like this in XML:
+
+```xml
+<bean id="template" class="org.springframework.data.mongodb.core.MongoTemplate">
+  <constructor-arg>
+    <bean class="com.mongodb.MongoClient">
+       <constructor-arg value="localhost" />
+       <constructor-arg value="27017" />
+    </bean>
+  </constructor-arg>
+  <constructor-arg value="database" />
+</bean>
+
+<mongo:repositories base-package="com.acme.repository" />
+```
+
+This will find the repository interface and register a proxy object in the container. You can use it as shown below:
+
+```java
+@Service
+public class MyService {
+
+  private final PersonRepository repository;
+
+  @Autowired
+  public MyService(PersonRepository repository) {
+    this.repository = repository;
+  }
+
+  public void doWork() {
+
+     repository.deleteAll();
+
+     Person person = new Person();
+     person.setFirstname("Oliver");
+     person.setLastname("Gierke");
+     person = repository.save(person);
+
+     List<Person> lastNameResults = repository.findByLastname("Gierke");
+     List<Person> firstNameResults = repository.findByFirstnameLike("Oli*");
+ }
+}
+```
+
+## Contributing to Spring Data
+
+Here are some ways for you to get involved in the community:
+
+* Get involved with the Spring community on Stackoverflow and help out on the [spring-data-mongodb](http://stackoverflow.com/questions/tagged/spring-data-mongodb) tag by responding to questions and joining the debate.
+* Create [JIRA](https://jira.springframework.org/browse/DATADOC) tickets for bugs and new features and comment and vote on the ones that you are interested in.  
+* Github is for social coding: if you want to write code, we encourage contributions through pull requests from [forks of this repository](http://help.github.com/forking/). If you want to contribute code this way, please reference a JIRA ticket as well covering the specific issue you are addressing.
+* Watch for upcoming articles on Spring by [subscribing](http://spring.io/blog) to spring.io.
+
+Before we accept a non-trivial patch or pull request we will need you to sign the [contributor's agreement](https://support.springsource.com/spring_committer_signup).  Signing the contributor's agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do.  Active contributors might be asked to join the core team, and given the ability to merge pull requests.

-== Running CI tasks locally
-
-Since Concourse is built on top of Docker, it's easy to:
-
-* Debug what went wrong on your local machine.
-* Test out a a tweak to your `test.sh` script before sending it out.
-* Experiment against a new image before submitting your pull request.
-
-All of these use cases are great reasons to essentially run what Concourse does on your local machine.
-
-IMPORTANT: To do this you must have Docker installed on your machine.
-
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-8-jdk-with-mongodb /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
-+
-Next, run the `test.sh` script from inside the container:
-+
-2. `PROFILE=none spring-data-mongodb-github/ci/test.sh`
-
-Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
-
-If you need to test the `build.sh` script, do this:
-
-1. `mkdir /tmp/spring-data-mongodb-artifactory`
-2. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github --mount type=bind,source="/tmp/spring-data-mongodb-artifactory",target=/spring-data-mongodb-artifactory springci/spring-data-8-jdk-with-mongodb /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github` and the temporary
-artifactory output directory at `spring-data-mongodb-artifactory`.
-+
-Next, run the `build.sh` script from inside the container:
-+
-3. `spring-data-mongodb-github/ci/build.sh`
-
-IMPORTANT: `build.sh` doesn't actually push to Artifactory so don't worry about accidentally deploying anything.
-It just deploys to a local folder. That way, the `artifactory-resource` later in the pipeline can pick up these artifacts
-and deliver them to artifactory.
-
-NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

-# Benchmarks
-
-Benchmarks are based on [JMH](https://openjdk.java.net/projects/code-tools/jmh/).
-
-# Running Benchmarks
-
-Running benchmarks is disabled by default and can be activated via the `benchmarks` profile.
-To run the benchmarks with default settings use.
-
-```bash
-mvn -P benchmarks clean test
-```
-
-A basic report will be printed to the CLI.
-
-```bash
-# Run complete. Total time: 00:00:15
-
-Benchmark                                    Mode  Cnt        Score       Error  Units
-MappingMongoConverterBenchmark.readObject   thrpt   10  1920157,631 ± 64310,809  ops/s
-MappingMongoConverterBenchmark.writeObject  thrpt   10   782732,857 ± 53804,130  ops/s
-```
-
-## Running all Benchmarks of a specific class
-
-To run all Benchmarks of a specific class, just provide its simple class name via the `benchmark` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark
-```
-
-## Running a single Benchmark
-
-To run a single Benchmark provide its containing class simple name followed by `#` and the method name via the `benchmark` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark#readObjectWith2Properties
-```
-
-# Saving Benchmark Results
-
-A detailed benchmark report is stored in JSON format in the `/target/reports/performance` directory.
-To store the report in a different location use the `benchmarkReportDir` command line argument.
-
-## MongoDB
-
-Results can be directly piped to MongoDB by providing a valid [Connection String](https://docs.mongodb.com/manual/reference/connection-string/) via the `publishTo` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D publishTo=mongodb://127.0.0.1:27017
-```
-
-NOTE: If the uri does not explicitly define a database the default `spring-data-mongodb-benchmarks` is used. 
-
-## HTTP Endpoint
-
-The benchmark report can also be posted as `application/json` to an HTTP Endpoint by providing a valid URl via the `publishTo` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D publishTo=http://127.0.0.1:8080/capture-benchmarks
-```
-
-# Customizing Benchmarks
-
-Following options can be set via command line.
-
-Option | Default Value
---- | ---
-warmupIterations | 10
-warmupTime | 1 (seconds)
-measurementIterations | 10
-measurementTime | 1 (seconds)
-forks | 1
-benchmarkReportDir | /target/reports/performance (always relative to project root dir)
-benchmark | .* (single benchmark via `classname#benchmark`)
-publishTo | \[not set\] (mongodb-uri or http-endpoint)

+# MongoDB Log4J Appender
+
+This module sets up a Log4J appender that puts logging events in MongoDB. It is fully configurable
+and connects directly to the MongoDB server using the driver. It has no dependency on any Spring package.
+
+To use it, configure a host, port, (optionally) applicationId, and database property in your Log4J configuration:
+
+    log4j.appender.stdout=org.springframework.data.mongodb.log4j.MongoLog4jAppender
+    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
+    log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n
+    log4j.appender.stdout.host = localhost
+    log4j.appender.stdout.port = 27017
+    log4j.appender.stdout.database = logs
+    log4j.appender.stdout.collectionPattern = %c
+    log4j.appender.stdout.applicationId = my.application
+    log4j.appender.stdout.warnOrHigherWriteConcern = FSYNC_SAFE
+
+It will even support properties in your MDC (so long as they're Strings or support .toString()).
+
+The collection name is configurable as well. If you don't specify anything, it will use the Category name.
+If you want to specify a collection name, you can give it a Log4J pattern layout format string which will have
+the following additional MDC variables in the context when the collection name is rendered:
+
+    "year" = Calendar.YEAR
+    "month" = Calendar.MONTH + 1
+    "day" = Calendar.DAY_OF_MONTH
+    "hour" = Calendar.HOUR_OF_DAY
+    "applicationId" = configured applicationId
+
+An example log entry might look like:
+
+    {
+      "_id" : ObjectId("4d89341a8ef397e06940d5cd"),
+      "applicationId" : "my.application",
+      "name" : "org.springframework.data.mongodb.log4j.MongoLog4jAppenderIntegrationTests",
+      "level" : "DEBUG",
+      "timestamp" : ISODate("2011-03-23T16:53:46.778Z"),
+      "properties" : {
+        "property" : "one"
+      },
+      "message" : "DEBUG message"
+    }
+
+To set WriteConcern levels for WARN or higher messages, set warnOrHigherWriteConcern to one of the following:
+
+* FSYNC_SAFE
+* NONE
+* NORMAL
+* REPLICAS_SAFE
+* SAFE
+
