Just to follow-up on this. There is/was indeed a bug here and under load
(only duplicated me for on an 8-core system)
AsynchronousFileChannel.write could complete immediately and invoke the
completion handler with the incorrect number of bytes. This has been
fixed for jdk7 b81, which is due 1/28 . Thanks for bug report and the
information needed to duplicate this.
