svn commit: r730420 - /incubator/jspwiki/trunk/src/com/ecyrd/jspwiki/auth/SessionMonitor.java

New Revision: 730420

URL: http://svn.apache.org/viewvc?rev=730420&view=rev
Log:
SessionMonitor now calls WikiEngine.shutdown() when the webapp context is 
unloaded. It didn't before, which meant containers would accumulate threads and 
eventually exhaust memory.
