This exception class is thrown when application deadlock is detected when trying to lock an entity bean This is probably NOT a result of a jboss bug, but rather that the application is access the same entity beans within 2 different transaction in a different order. Remember, with a PessimisticEJBLock, Entity beans are locked until the transaction commits or is rolled back.
