> Running a strongly threadded Eclipse application using xmlbeans in multi-processor (/multi-core)
computer causes frequent crashes in xmlbeans code. 
> Most of the crases happen in Cur.java in form of a NPE:

> ***************************************************
> This problem problem occurs in xmlbeans 2.2. and in the latest version in SVN. The problem
disappears when I turn the multi-core support off from BIOS and reappears again immediently
when I turn it back on. So I believe that this has something to do with threading. Only classes
Locale.java and Cur.java seem to be affected. I haven't encountered any exceptions from other
classes.
