Good suggestion!! :) Yes, an ExceptionListener on the Connection does get the exception when ResourceAllocationException is thrown.
Of course, I could hack my way around it, notifying the client from the connection when the connection receives the error, but that seems backwards to me…. the error is sent in another thread, so I have no guarantee that the client is notified in time to avoid committing after an error occurs. (and honestly, returning from commit() without errors when all my messages have been discarded seems to be a strange transactional contract…. even if error notification is sent in another channel) I could not find an existing issue that describes this problem, so I'm going to post a bug report of the problem.
