------------------------------------

             Summary: Cleanup creates new generation of tar file without 
removing any segments 
                 Key: OAK-4669
                 URL: https://issues.apache.org/jira/browse/OAK-4669
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: segment-tar
    Affects Versions: Segment Tar 0.0.8
            Reporter: Andrei Dulceanu
            Assignee: Andrei Dulceanu
            Priority: Minor
             Fix For: Segment Tar 0.0.10


On some deployments I have seen tar files with a quite hight generation 
post-fix (e.g. 'v'). From the log files I could deduce that this particular tar 
file was rewritten multiple times without actually any segment being removed.
I assume this is caused by the 25% gain threshold not taking the sizes 
contributed by the index and the graph entries into account.

The attached test case can be used to verify the above hypothesis
