Description

After initialization of the AxisServlet, the initialization of the AxisAdminServlet associates to the ConfigurationContext (Shared amongs AxisServlets) a new ListenerManager overriding the existing one.
The Listermanager.stop() method is never called on the old one so the system shutdown hook is never removed causing the object to be skipped form the garbage collection.
This causes a memory leak and the following OutOfMemoryError: PermGen after the axis2 application is reloaded several times.
