Empty query results after JAR creation

Hi, I struggle with a strange issue. I've embedded ObjectDB in a small application to query cases.

I've created a small test case (attached zip file) with sample DB to reproduce the issue.  ... That file is probably empty you can check it in the Explorer. > The Size of both DB files is exactly the same ...

The problem is that ObjectDB loads all the classes in P1 (+ the ...
