The problem (and solution) are exactly the same under JDK1.3 and JDK1.4.
Due to the nature of OSGi, which uses modular classloaders, the Xerces.jar is 
not on the classpath. It is loaded by a custom classloader.

This does always work - but it means every single thread that is created in the 
VM has to remember to set it's context classloader - which is a total pain. In 
every case, the solution is "set context classloader from 
this.class.classloader" - 
which implies to me that Xerces could have this as a fallback option if a class 
is 
not found through the thread context classloader.
