DelegatedExecutorService disables thread dump in stuck threads warning

In Threads.shutdown[Daemon] if the ExecutorService doesn't terminate, a warning is displayed which details the stack trace of the thread(s) that are preventing shutdown.

This works only when the ExecutorService is a ThreadPoolExecutor.

Unfortunately in java.concurrrent.Executors it's quite common to get back an executor service wrapped in some flavour of java.util.concurrent.Executors.DelegatedExecutorService.

It would be good if we could resolve the delegation in order to find a ThreadPoolExecutor to make that warning more useful.
