             Summary: Memory leak in remoting-jmx
                 Key: REMJMX-94
                 URL: https://issues.jboss.org/browse/REMJMX-94
             Project: Remoting JMX
          Issue Type: Bug
    Affects Versions: 1.1.3.Final
            Reporter: Libor Zoubek
            Assignee: Darran Lofthouse


In RHQ plugin We're experiencing a memory leak when we talk to EAP over remoting-jmx. Leak is very notable once we restart our plugin container (each plugin has in it's own classloader) Classes owned by RHQ Server plugin don't get GCed.

I am able to reproduce mem leak without RHQ agent and plugin infrastructure repeating following steps:

1. start new thread
2. assign URL classloader to this thread (point it to jboss-client.jar)
3. connect & disconnect to jmx-remoting endpoint

In this test no classes don't get GCed which after serveral iterations ends up in OOM.

My test/example is here https://github.com/lzoubek/remotingjmx-leak/blob/master/src/main/java/org/jboss/remotingjmx/memleak/test/Main.java

I am not sure if memleak is in remoting-jmx or some other underlying stuff. 

I thought https://issues.jboss.org/browse/REM3-200 was related, but workaround mentioned does not help.
