I instantiate the Tomcat object and invoke start() on the "main" thread. The invocation of ServletContextListeners happens on a "localhost-startStop-1" thread. I would like to have that invocation happen on the main thread instead. Its nothing within tomcat that is deadlocking, but under the covers weld has a synchronized block, its inside that synchronized block where Tomcat is instantiated. There's a later point where Weld tries getting a lock again. In that case, when its single threaded (in other containers) it passes since it has a lock, but in this case it can't get that lock. > > Mark > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org > For additional commands, e-mail: users-h...@tomcat.apache.org > >
