             Summary: Use of TP.internal_pool can result in classloader leaks
                 Key: JGRP-2244
                 URL: https://issues.jboss.org/browse/JGRP-2244
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 4.0
            Reporter: Paul Ferraro
            Assignee: Bela Ban


As of JGroups 4.0, the ThreadFactory of the internal thread pool cannot be overridden.  Consequently, there is no mechanism to associate newly spawned threads with a specific classloader.  If an application thread results in the spawning of an thread in this internal pool [1], the application class loader can leak to other threads used the the JGroups channel.
