At present, the insert of new attributes in JdbcOperationsSessionRepository is done unconditionally. This can cause data integrity violation errors with concurrent requests, where one request attempts to add new session attribute while the other, concurrent request, deletes the session. This commit addresses the described scenario by executing insert of new attributes conditionally on presence of parent record. Closes gh-1153

This provides many benefits including: * Accessing a session from any environment (i.e. web, messaging infrastructure, etc) * In a web environment ** Support for clustering in a vendor neutral way ** Pluggable strategy for determining the session id ** Easily keep the HttpSession alive when a WebSocket is active == Code of Conduct This project adheres to the Contributor Covenant link:CODE_OF_CONDUCT.adoc[code of conduct].
