This works fine using webwork 2.2.2, however i cant updgrade due to this error.

I set up a simple project with a 'HelloWorld' action, all works fine. Then on startup, i set this (which works fine in 2.2.2)

<code>
System.setProperty("javax.xml.transform.TransformerFactory", "net.sf.saxon.TransformerFactoryImpl");
</code>

and my action class wont run throwing this error:
