App Engine "sandbox" environment imposes some restrictions on what can be done. As it is stated in public documentation [1]: "... you must use one of the methods on ThreadManager to create your threads. You cannot invoke new Thread() yourself or use the default thread factory <http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/Executors.html#defaultThreadFactory> ."
...and that is what ServerMonitor.java is trying to do [2]. It looks like if a a workaround exists, it will not be trivial [3].
