Robert Stupp commented on CASSANDRA-11867:
------------------------------------------

Thanks!
Committed as ffd10a9b9a391f6bb55daa7e9365bff34f945f73 to 2.2, as 
361c4e4c7000bcfded4ea81f6ebd59eeed42ab31 to 3.0 and merged to 3.7 and trunk.

Yes, accessing a closed stream is never a good idea. But better to error out 
fast instead of leaving it in a weird state.

> {{NIODataInputStream}} allocates direct memory but does not clean it on 
> close. Proposed patch adds a call to {{FileUtils.clean()}} for this direct 
> memory buffer.
