Inspect ExecutorService details

Is there a way to dig into an ExecutorServer object to see how many threads are currently being used?

if (executor instanceof ThreadPoolExecutor) {
    int poolSize = ((ThreadPoolExecutor) executor).getPoolSize();
    // or
    int currentlyActive = ((ThreadPoolExecutor) executor).getActiveCount();
}

But generally, you should know that, because you have constructed the service (unless it is hidden in some bad API)
