Null Exception

#1

An user reported me this exception. I am not sure how to reproduce it, but maybe it can help you to solve it somehow.  Object DB 2.4.4_05, embedded

The important part is:

null

This could be the result of sharing entities by different threads.

It may help if you could provide a test application that consistently causes this exception (even without isolating it into a small test case).
