All code should be switching and restoring the classloader
during the invocations. Anything else is a bug.
ClassLoader old = tcl;
tcl = myClassLoader
try
{
}
finally
{
tcl = old;
}
Of course if something (e.g. an MBean)
that is hotdeployed starts a thread
and doesn't stop it at undeployment then it will leak
the classloader. But that is also a bug.

I meant that because of references through ThreadWithAttributes (they will be always appear for some reason on JVMTI). Anyway, I need to know if a Thread is cleared (Thread.setContextClassLoader(somethingElse) before the Thread goes to sleep. If the Thread keeps the ClassLoader reference until next request, that will make my life harder creating a TestCase structure for testing redeployment/classLeakages. http://jira.jboss.org/jira/browse/JBAS-2909 -Original Message- From: Adrian Brock Sent: Thursday, March 23, 2006 3:41 AM To: Clebert Suconic Cc: Scott M Stark; jboss-development@lists.sourceforge.net Subject: Re: FW: JBAS-2972 - OOME / Redeployment leakages On Wed, 2006-03-22 at 21:03 -0600, Clebert Suconic wrote: > Sorry... pressed Ctrl-enter instead of Enter.
