get a npe with the most
simple test (retrieving the root node):

> Replace Xerces/JAXP based (un)marshalling by XPP3 based implementation
> ----------------------------------------------------------------------
>
> Key: JCR-1261
> URL: https://issues.apache.org/jira/browse/JCR-1261
> Project: Jackrabbit
> Issue Type: Improvement
> Components: jackrabbit-webdav
> Affects Versions: 1.3.3
> Reporter: Felix Meschberger
> Attachments: JCR-1261.patch, JCR-1261_2.patch
>
>
> Proposing to replace the current Xerces/JAXP based implementation of XML data
> unmarshalling and marshalling to be replaced by a MXP ([1]) based
> implementation. MXP is an implementation of the XML PullParser API [2] and
> provides a very mall footprint (120KB) and far better performance than Xerces
> (my tests showed around 50% performance increase over Xerces for both
> unmarshalling and marshalling, see also [3]).
> Why do I care ? I would like to include WebDAV functionality into Sling and
> bundle is with as little dependencies as possible ( the xpp3 lib might even
> be bundled into this project to minimize dependencies). In addition, I think
> XML (un)marshalling performance is crucial in any WebDAV solution. For this
> reason, this project can only win if we add a more performing library.
