 Review comment:
   I see now. .the issue is that a stop(shutdown=true) should clear the activateCallbacks. 
   
   this is not really an issue when running on a real server, but if you call shutdown=true, it means the VM is going down and the process should cleanup anything left behind.
   
   As the callback is leaking, if you reused the server after a stop(shutdown=true) on the testsuite, you will have the activation (on this case the one holding the lock) being called an extra time, what would then cause the file leak.
   
   
   I will send another PR with checking the shutdown clause and add a test to avoid a future leak.
