ODB tries to create log files inside its own jar on Win7

I sent a demo of an app I've been developing on Linux to some Windows 7 users, and they were unable to run it.  The stack traces they sent me indicated that ODB was trying to create its log files inside objectdb.jar, which was inside the executable jar packaged by Eclipse.  Here's the end of the stack trace: ... using, with its own clean workspace.  I created a new project, added objectdb.jar to the build path as an external jar, and wrote ...

IDs of Entities suddenly became UUIDs?

Hi, We're having our system with ObjectDB 2.4.5 in production since this year April and it works just fine. However, now we've discovered that suddenly partial Objects in some DBs in production do have a UUID String as their id instead of Long which is of course causing a lot of troubles.

persistence.xml classes not respected by ObjectDB

Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ their embeddable classes). P2 is created properly, but P1 gets all entity classes (from P2 also). How can this be avoided, so that both P1 and P2 get just the classes that were specified to each? There is no place in code where P1 tries to access classes from P2, so it makes no sense. ... bit more problematic, because it's already a very big project. So, the bottom line is that ODB seems to do not respect the ...
