Memory leak in TransactionReaper._timeouts
------------------------------------------

                 Key: JBTM-352
                 URL: http://jira.jboss.com/jira/browse/JBTM-352
             Project: JBoss Transaction Manager
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Transaction Core
    Affects Versions: 4.3.0.GA
         Environment: Compiled 4.3.0.GA for the EAP 4.3 as JTS according to the instructions (by setting JBOSS_HOME to jboss-5.0.0.Beta4) on RHEL4.
Run ~ 1500 JMS transactions in EAP 4.3 all configuration on RHEL4 to see it leaks.
Used Sun jdk 1.5.0.14 
            Reporter: Ivan Szanto


The leak can also be seen by using the debugger to check the number of entries in TransactionReaper._timeouts after a couple of transactions.
It appears that the TransactionReaper.insert method uses ControlWrapper objects as keys when putting elements into the hashtable, but the TransactionReaper.remove method sometimes unsuccessfully tries to use Uid ojbects to remove them.

I will post a corrected version of TransactionReaper.java.
