Philippe Marsteau commented on XMLBEANS-328:
--------------------------------------------
Is the patch part of the latest XBean release? We experience same issue with
xbean-2.2.0a.jar and wish to know if it would be wiser to upgrade to latest
version or to patch existing one (using 2.2.0 patch).
Thanks for following-up to any who had this issue and got it fixed using either
latest release or published patch.

> 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:
> ***************************************************
> java.lang.NullPointerException

> ***************************************************
> 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.
