Stefan Bodewig updated COMPRESS-253:
------------------------------------
Attachment: compress-253.patch
The reason for this is that BZIp2CompressorInputStream always calculates the
next byte when reading one.
The attached patch (against current trunk) changes this and removes a piece of
state at the same time. All existing tests inside Common Compress pass with
the change but we are pretty close to release 1.7 and I don't feel well adding
the change now without more extensive testing.
> BZip2CompressorInputStream reads less bytes from truncated file than
> CPython's bz2 implementation

> Jython includes support for decompressing bz2 files using commons compress

> The BZip2CompressorInputStream is able to read 769 bytes from the truncated
