>> The destroy, isDestroyed, setDaemon, isDaemon methods support the mechanism to explicitly or automatically destroy a thread group. As detailed in JDK-8252885, the mechanism to destroy thread groups is flawed and racy. Furthermore, this mechanism inhibits efforts to drop the reference from a thread group to its threads (so that thread creation, starting and termination do not need to coordinate with their thread group). These methods should be terminally deprecated so they can be degraded in a future release and eventually removed.
