    Late Or Wrong Detected Deadlocks ?

    Markus Kehrer Newbie

      Environment:
      JBoss 3.2.7; J2EE 1.3.1; JDK 1.4.2_11; MSSQL 2005;

      Problem:
      We have observerd that a QueuedPessimisticEJBLock is detected (too late?) after a object has been accessed several times before, already...

      I'm confused, cause no lock has been detected while seveal 'isSomethingTrue' or 'getSomething' methods of 'ExampleLocal' have been invoked in the same method, before 'checkSomethingOfExample' is called.

      Does anybody understand whats happening here and is able to explain this behavior?
