[jira] Created: (AXIS2-3861) Should be an option to disable
ShutdownHook of ListenerManager
Should be an option to disable ShutdownHook of ListenerManager
--------------------------------------------------------------
Key: AXIS2-3861
URL: https://issues.apache.org/jira/browse/AXIS2-3861
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: kernel
Reporter: Sergey Vladimirov
Fix For: nightly
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()

----------------------------------------
I don't see the need to disable the shutdown hook. However ListenerManager#stop should remove it using Runtime#removeShutdownHook. Otherwise this will indeed cause a memory leak.
