> We found out that when the transaction manager "reaper" thread rolls back a transaction, it doesn't remove the transaction from a static collection.  tx.suspend, which disassociates the transaction from the application thread, also doesn't remove the transaction from the static collection.  As a result, the transaction leaks and all of the objects references by it (including all resources that are put there like JPA persistence contexts).
> To address this, we should change org.jboss.as.ejb3.tx.CMTTxInterceptor.endTransaction (STATUS_ROLLEDBACK case in switch statement) to call tm.rollback() instead of tm.suspend().
