Subject [jira] Created: (AMQ-2138) Memory Leak in ActiveMQConnection
Date Mon, 23 Feb 2009 10:26:59 GMT
Memory Leak in ActiveMQConnection

                 Key: AMQ-2138
             Project: ActiveMQ
          Issue Type: Bug
          Components: Connector
         Environment: Tomcat 6 + ActiveMQ 5.1
            Reporter: Markus Wolf

We discovered a memory leak in the ActiveMQConnection class.
In our setup we have an activemq 5.1 embedded in our webapplication. On undeployemnt (more
specially on connection close) the ThreadPoolExecutor is kept in memory and could not be garbage
collected, because of the ThreadFactory which is loaded by our webapp classloader. A reference
to it is held by the ThreadPoolExecutor.
This is likly a bug in the JDK TheadPoolExecutor but it could be fixed by setting a default
ThreadFactory before shutdown.
