[jboss-user] [IronJacamar] - Possible mem leak in TX synchronizer on afterCompletion() phase

Andrey Smirnov [https://community.jboss.org/people/cheezzario] created the discussion "Possible mem leak in TX synchronizer on afterCompletion() phase" To view the discussion, visit: https://community.jboss.org/message/831719#831719 -------------------------------------------------------------- Hello. Let me introduce the problem App server ( jboss-as-7.1.1.Final ) which is a part of complex distributed app using CORBA for communication fails with OutOfMemoryError I've investigated the problem and seems like root cause is inability  to clean up txSynchs ( and locks ) maps resided in org.jboss.jca.core.connectionmanager.transaction.TransactionSynchronizer class. More detailed: Collections mentioned above should be cleaned up in afterCompletion() method but TX is unavailable at that stage, so Transaction.hashCode() returns -1 which leads to dangled TX associations. Right now I don't understand why javax.transaction.Transaction is used as a key in this maps? For me it seems like this code wil always fail. I've attached modified source code of  TransactionSynchronizer which I used during investigation and partial app log with records specific to one TX.
