FWIW when I run the test case in that bug on the latest JDK 23 (jdk-23+21-110-g0a4eeeaa3c6), it does not report any exception.

So this bug may have gotten fixed by recent changes and just needs to be closed... ?

Interesting observation, I can confirm this with 23+EA-22.

 

However, for my corrupt sample ZIPs, it still fails:

So maybe there are two different causes.

 

I made some progress in regards to identifying the source,
the file in question is probably generated with POI.

 

I hope I can share a publishable file soon - keep you posted.
