Description

PTFOperator::initializeOp() does not reset currentKeys to null.

      if (currentKeys != null && !keysAreEqual) {
        ptfInvocation.finishPartition();
      }
....
      if (currentKeys == null) {
          currentKeys = newKeys.copyKey();
        } else {
          currentKeys.copyKey(newKeys);
        }
