Hallo,
i am running an application (Spring+Framework+Quartz) in tomcat 6.0.18 under
Windows XP and JDK 1.6.0_16. When i shutdown tomcat (either script or
SHUTDOWN via 8005 port), there are always some threads hanging. They are not
related to the application, as far as i can see- although it problems with
"Spring+Framework+Quartz". The thread stack follows; i can see some locks
there... Does somebody have some advice? I am new in Tomcat (and threaded
debugging) so any directions would be appreciated....
