If I understand correctly, you modify the bytecode to insert checks before it loops back ? Pretty cool. I haven't looked too much at the code - do you do it via a generic ClassLoader ?

I'm wondering if the JVM itself wouldn't be a better place to implement this functionality ( i.e. a safe implementation of Thread.stop() ) Costin lgis Rudys wrote: > Greetings -- > > As I announces about a week ago, as a part of my research, I have > developed a mechanism for terminating individual Tomcat webapps (at the > context level) called soft termination.
