Returns the pool hosting this thread.
Returns the unique index number of this thread in its pool. The returned value ranges from zero to the maximum number of threads (minus one) that may exist in the pool, and does not change during the lifetime of the thread. This method may be useful for applications that track status or collect results per-worker-thread rather than per-task.
Initializes internal state after construction but before processing any tasks. If you override this method, you must invoke {@code super.onStart()} at the beginning of the method. Initialization requires care: Most fields must have legal default values, to ensure that attempted accesses from other threads work correctly even before this thread starts processing tasks.
Performs cleanup associated with termination of this worker thread. If you override this method, you must invoke {@code super.onTermination} at the end of the overridden method.
This method is required to be public, but should never be called explicitly. It performs the main run loop to execute {@link ForkJoinTask}s.
Non-hook method for InnocuousForkJoinWorkerThread.
If the current thread is operating in a ForkJoinPool, unschedules and returns, without executing, a task externally submitted to the pool, if one is available. Availability may be transient, so a {@code null} result does not necessarily imply quiescence of the pool. This method is designed primarily to support extensions, and is unlikely to be useful otherwise.
A worker thread that has no permissions, is not a member of any user-defined ThreadGroupEx, uses the system class loader as thread context class loader, and erases all ThreadLocals after running each top-level task.
