JSC 1.3 thread cleanup

[Tim Cronin]

I'm getting tomcat errors on shutdown:

2015-01-22 16:41:51,186 [localhost-startStop-2] ERROR
org.apache.catalina.loader.WebappClassLoader- The web application
[/api] appears to have started a thread named
[ElementEventQueue.QProcessor-1] but has failed to stop it. This is very l
ikely to create a memory leak.

i tracked it down to

org.apache.jcs.engine.control.CompositeCache:

    /**
     * EventQueue for handling element events. 1 should be enough for all
the regions. Else should
     * create as needed per region.
     */
    public static IElementEventQueue elementEventQ = new ElementEventQueue(
"AllRegionQueue" );

then calling CompositeCache.elementEventQ.destroy();

but it can be flaky and IMO should be handled via
CompositeCacheManager.shutdown().

is there a better way to handle this and do i need to file a bug on this?
