This method is introduced in nio spec v 0.39.

It throws NegativeArraySizeException when offset > length.

This is inconsistent with spec.

For example,
   // write out remaining bytes from srcBuffers[2] only
   fc.write(srcBuffers, 2, 1) ;

---------------------------
java.lang.NegativeArraySizeException
        at sun.nio.ch.Util.subsequence(Util.java:22)
        at sun.nio.ch.FileChannelImpl.write(FileChannelImpl.java:179)
        at FCgatheringWriteSubseq.writeGatheringTest02(FCgatheringWriteSubseq.java:254)
---------------------------

Also, when offset < length it does not write out correct data from src
Buffers to FileChannel.

For example,
   // write out remaining bytes from srcBuffers[1] and srcBuffers[2]
   fc.write(srcBuffers, 1, 2) ;
