ensureThreadContext

boolean ensureThreadContext()

The RequestContext itself is kept in a ThreadLocal, calling this method from another (parallel) thread ensures its ThreadLocal instance will be synchronized with this instance as well.

This method will return true if this thread its ThreadLocal didn't yet have this RequestContext value set. In that case the calling code block, preferably in a finally statement should call clearThreadContext() to ensure the reference to this instance is removed again from its ThreadLocal instance as Thread Pool solutions might reuse threads.

true if the current thread didn't have this request context set or contained a different (stale/left over?) request context

Clears the request context from the current thread
