Description of problem:

unbounded-queue-thread-pool treats all threads as core threads (core-threads inherently equals max-threads) and so they don't timeout.  Given this expected behavior, it may make more sense to not allow the keepalive-time parameter in this executor config and/or have the pool size configured through core-threads instead of max-threads (so it's clearer that all threads will be considered core threads).
