Any threads that are still running will keep the Java (Tomcat) process alive. Make sure all your threads exit. Once your threads exit, Tomcat will be able to shut down.

See the javadoc for Thread. Note the following:

• The exit method of class Runtime has been called and the security manager has permitted the exit operation to take place.
• All threads that are not daemon threads have died, either by returning from the call to the run method or by throwing an exception that propagates beyond the run method.
