Bela Ban resolved JGRP-2244.
----------------------------
    Resolution: Done


Added methods to get and set both the internal pool itself and the associated thread pool factory. You may want to use {{setInternalThreadPool()}} directly...

> 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.
