>             Project: MINA
>          Issue Type: Bug
>          Components: Filter
>    Affects Versions: 1.1.7, 2.0.0-M1, 2.0.0-M2, 2.0.0-M3, 2.0.0-M4, 2.0.0-M5, 2.0.0-M6, 2.0.0-RC1
>            Reporter: Yannick Lecaillez
>            Priority: Trivial
>   Original Estimate: 1h
>  Remaining Estimate: 1h
>
> Zlib.deflate() method is using 
> IoBuffer.wrap(outBytes, 0, zStream.next_out_index);
> rather than
> IoBuffer.wrap(outBytes, 0, zStream.avail_out);
> That introduce invalid data in the wrapped buffer: (looks like next_out_index = avail_out + 1)
> Replacing zStream.next_out_index by avail_out fix the issue.
