Research direction

Start with ServerSessionImpl.start() and trace how it handles failures from the WorkManager, then check the related Geronimo WorkManager behavior described in GERONIMO-6911. Consider the reported RejectedExecutionException case and verify that the session does not remain stuck; the issue gives no test file, so locate the relevant session tests and run them.

Written by the indexing model from the issue text.

Description

ServerSessionImpl.start() only catches WorkException which should arguably be sufficient. However, the GeronimoWorkManager might throw a plain RejectedExecutionException. See GERONIMO-6911

I do think it's an upstream bug, but widening the catch clause seems like a good idea regardless.
