JBoss uses
pessimistic locking. So as an entity bean is accessed within a transaction
it is pessimistically locked.
What if the thread
that is the transaction is tied up blocking forever on I/O? Yes, the TM
will mark the transaction as rolled back, but the entity beans locked within the
transaction will not be released because the thread will never wakeup and
realize it must do a rollback. Am I wrong here?
