Description

Axis2 is loaded several times using different classloaders. In every classloader ListenerManager register new Shutdown Hook:

Runtime.getRuntime().addShutdownHook(new ListenerManagerShutdownThread(this));

So, every call to AxisServlet (in new classloader) leak 500 Kb of memory.

There is should be an option in AxisServlet and ListenerManager to disable shutdown hook. Anyway, stop() method is promiced to be called from AxisServlet::destroy() => ConfigurationContext::terminate()
