Václav Haisman commented on COMPRESS-589:
-----------------------------------------
I think I have possibly found an issue in our code. What we do is that we
iterate over input TAR file and we copy most entries into output TAR file. But
some entries are modified in the process and those change size. We were reusing
{{TarArchiveEntry}} instance, only setting the size, we got from
{{getNextTarEntry}} as input for the output TAR file. When I rewrote the code
to copy the {{TarArchiveEntry}} into new instance, out test started passing.
Does this mean any instance of {{TarArchiveEntry}} is tied to the originating
stream and cannot be reused elsewhere?
