public abstract ForkJoinWorkerThread newThread (ForkJoinPool pool)

Returns a new worker thread operating in the given pool. Returning null or throwing an exception may result in tasks never being executed. 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).

Parameters
pool ForkJoinPool: the pool this thread works in

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

Throws
NullPointerException if the pool is null
