      public static java.lang.Throwable tryInternalFastPathGetFailure​(InternalFutureFailureAccess future)
      Usually returns null but, if the given Future has failed, may optionally return the cause of the failure. "Failure" means specifically "completed with an exception"; it does not include "was cancelled." To be explicit: If this method returns a non-null value, then:
      • isDone() must return true
      • isCancelled() must return false
      • get() must not block, and it must throw an ExecutionException with the return value of this method as its cause
