I got the following printed to the console at startup:

(note: I didn't see these error messages in the log, which scares me)

Would you have a reproducable test case? It looks really weird, that this exception could occur.

Comment 2 Jed Anderson

Sorry, I have no test case.

I imagine it is a rare timing issue since I have been running a large number of 
workspaces against this code and have only seen the walkback once.

Now caching the zip file on a per thread basis. This will prevent 2 threads to 
use the same ZipFile instance.
