memory leak in DeadlockDetector
-------------------------------

                 Key: JBAS-7710
                 URL: https://jira.jboss.org/jira/browse/JBAS-7710
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: JBossAS-4.0.5.GA
         Environment: JBoss 4.0.5.GA with JBOSSTS_4_2_3_SP7
            Reporter: Michal Borowiecki

Heap dump diagnostics revealed a memory leak in org.jboss.util.deadlock.DeadlockDetector.
The more deadlocks are detected  the more "waiting" HashMap is growing.

In our case the HashMap is >311MB in size. It contains 20 entries, 15 of them are > 20MB in size.
The large size is not caused by map values but rather map keys which are of type com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple and contain a large number (couple thousand) of org.jboss.ejb.EntityEnterpriseContext references in its _txLocalResources variable.
