Speed up marshalling objects to XML by explicitly loading classes

[Ben V]

I have lots of xsd and create java classes from them (~1000 classes) using
xjc and deployed them to Servicemix4 as an OSGI bundle.
Then I have application where I process the request and set exchange body to
some object from generated classes.
The problem is when it processes the first request - it takes around ~10
seconds (JAXB to marshal object and set Exchange Body to XML??).
Other requests runs without any time loss...

Is there a way to speed up first request and explicitly load all generated
classes when I deploy my bundle?
