If this method throws an exception, it is relayed to the caller of the method (for example execute) causing attempted thread creation. If this method returns null or throws an exception, it is not retried until the next attempted creation (for example another call to execute).

Returns:ForkJoinWorkerThread

the new worker thread, or null if the request to create a thread is rejected
