Stefan Bodewig resolved COMPRESS-140.
-------------------------------------

       Resolution: Fixed
    Fix Version/s: 1.2

Patch applied in svn revision 1148784, thanks!

I expect the concrete implementation of the fix to change before the release so I'd love to have a regression test, unfortunately I can't include the AR you attached as testcase (likely not something we should re-distribute).

Any idea how we could create a real archive with empty ids fields?  The alternative would be to mock such an archive internally but if some command line Fu will do, I'd prefer to do that.

> I have found an ar file (it happens to be a .lib file) which has 6 ASCII spaces for both the UID and GID fields.
> This goes through {{ArArchiveInputStream.asInt}} which throws a NumberFormatException.
> I'm not sure what the correct behaviour is, but the 'ar' utility I have on hand shows 0/0 for uid/gid for the same file.
