Can someone help here ? It seems the stateName attribute of MANAGER or WEBMODULE Mbean is NOT getting set correctly if there are any servlet errors.
In particular, when Spring dispatcher servlet is failed to load then the applications state should be STOPPED. However, that does not seem to be the case. I even checked the SERVLET Mbean as well did not see the expected state. Is there anything wrong that I am doing ? Is this a BUG ? Using Tomcat 8.0.30.
