Michael Poindexter commented on LUCENE-4848:
--------------------------------------------
bq. It would also be interesting if this patch maybe solves the
ClosedChannelException problem on interrupt? The time window in MMap is very
short that the bug can happen (only after opening the channel, while mmap is
doing its work before the channel is closed).
I don't think this will change the behavior much at all. Before the patch the
channel was only open briefly (just long enough to do the map()), and after the
change it is the same.

> I have implemented 3 Directory subclasses using NIO2 API's (available on
> JDK7). These may be suitable for inclusion in a Lucene contrib module.
> See the mailing list at http://lucene.markmail.org/thread/lrv7miivzmjm3ml5
> for more details about this code and the advantages it provides.
> The code is attached as a zip to this issue. I'll be happy to make any
> changes requested. I've included some minimal smoke tests, but any help in
> how to use the normal Lucene tests to perform more thorough testing would be
> appreciated.
