Marius, 

See a previous answer on this topic: 
http://www.mail-archive.com/user@xmlbeans.apache.org/msg00836.html

We're still committed to have XMLBeans working with a 1.4 JDK, so we
cannot apply your patch right now. But starting with v3 we'll most
probably drop this requirement and your patch will come handy.
