6979009: (fc) FileChannel.read() fails to throw ClosedByInterruptException

[Xueming Shen]

  463             } catch (ClosedByInterruptException e) {
  464                 // target closed by interrupt as ClosedByInterruptException needs
  465                 // to be thrown after closing this channel.
  466                 assert !target.isOpen();
  467                 try {
  468                     close();
  469                 } catch (IOException ignore) {
  470                     // nothing we can do
  471                 }
  472                 throw e;


You are invoking "close()" directly in this case when interrupted, instead of
"marking" it closed as we do in all other cases. This might be a good thing to
do as the spec says "the interruped channel to be closed" (release file lock,
native resource...), but make the "transferToTrustChannel" special.

Otherwise, the change looks good.
