DO NOT REPLY [Bug 48038] New: Reading StyleSheet from offset != 0 reads from arbitrary locations in the stream

https://issues.apache.org/bugzilla/show_bug.cgi?id=48038

           Summary: Reading StyleSheet from offset != 0 reads from
                    arbitrary locations in the stream
           Product: POI
           Version: 3.5-FINAL
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: major
          Priority: P2
         Component: HWPF
        AssignedTo: dev@poi.apache.org
        ReportedBy: trejkaz@trypticon.org


This one has been around at least as far back as 3.0.1 (which is the first copy
of POI we have in our own vendor tree.)

For some reason a lot of documents still work even though this bug exists, so
the offset must be 0 fairly often.  Even so, this causes some nasty random
errors.

I added a unit test which exhibits the issue.  My own complete testing will
follow.
