Andreas, 

We are using Axiom 1.2.7 and wanted to patch in this fix. Can you let me know 
what changes that you made and how I can patch them in? If I go to the 
Subversion Commits tab, can I just put in the changes under revision #797814, 
or do I also need the ones from #823973 and #823978 as well?

Thanks

> StAXUtil uses a single XMLInputFactory or XMLOutputFactory instance (per 
> classloader). This means that it makes the assumption that these instances 
> are thread safe. However, there is nothing in the StAX specs that guarantees 
> that, and Sun's implementation in JDK 6 is not thread safe, at least with the 
> default properties [1] [2].
