Remarks

Performs an action when method #completeExceptionally(Throwable) is invoked or method #compute throws an exception, and this task has not already otherwise completed normally. On entry to this method, this task ForkJoinTask#isCompletedAbnormally. The return value of this method controls further propagation: If true and this task has a completer that has not completed, then that completer is also completed exceptionally, with the same exception as this completer. The default implementation of this method does nothing except return true.
