Support blank uid/gid fields
-----------------------------
Key: COMPRESS-140
URL: https://issues.apache.org/jira/browse/COMPRESS-140
Project: Commons Compress
Issue Type: Improvement
Components: Archivers
Affects Versions: 1.1
Reporter: Trejkaz
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.
