            Good catch.

            Nits:

            • The System.err.println on line 111 in the test seems gratuitous
            • On line 112 perhaps s/contains/equals/ since you're explicitly looking for the Timer objects

            Unfortuntaely the Timer threads have java.util.TimerThread on the stack, but this class is a private "implementation detail" class. To work across different JVMs I elected to just look for the word "Timer" - make sense?

            Will fix the println
