There is a static TxEntityMap within Container that maps transactions to
entities used within those transactions. Maybe the TM(or some registered
TxTimeoutListener(do TxTimeoutListeners actually exist?)) should loop
through this list and get access to each Entitiy's BeanLock and call
BeanLock.clearLocks or something like that? Or, maybe your way is better.
Shit, I thought I was done looking at this locking code(I bet you were too
;)
I don't have time to do this now. I'll log a bug about this.
