Steps to reproduce:
1 - Start Hudson service (service tomcat6-hudson start), ;
2 - Ensure Hudson is online;
3 - Stop Hudson service (service tomcat6-hudson stop);

Expected (within few seconds):
1 - Hudson service should be stopped (service tomcat6-hudson status);

Found (after many hours):
1 - Hudson service hung, full log below;
2 - The server can't stop by itself, so I need to 'kill -9' it.
