> In LUCENE-1540 TrecContentSource moved from Java's GZipInputStream to
> common-compress 1.0.
> This slowed down gzip decompression by a factor of 15.
> Upgrading to 1.1 solves this problem.
> I verified that the problem is only in GZIP, not in BZIP.
> On the way, as 1.1 introduced constants for the compression methods, the code
> can be made a bit nicer.
