It's probably a bug, but ... - it would help to have a clear reproducible test case

No EoD at the end and what's even worse, I recently ran out of Kleenex to wipe away my tears.

- take a look at my vaguely related webrev from yesterday to this mailing list.

Ok.

- I don't call zos.finish; I call zos.close which Works For Me.

Try it with very large files...see above! :-)

I mentioned zos.finish() before I ran to lunch because that's where I see the EoD actually written out to the stream in cscope.

Unfortunately I don't have a working debugger right now since Java is normally just coffee to me, hence my cry for help (I may change that situation in the next few hours).

Thanks for the feedback, it is appreciated.
