We have fixed a bug in this relation in 2.0.x (cant remember the
version, might be the 2.0m3).
In older versions you can work around this by adding an @Body
annotation to your base class
public void process(@Body String body)
And Camel should prefer to use this method.

Its on the HttpMessage instead.
HttpMessage in = (HttpMessag) exchange.getIn();
HttpServletRequest = in.getRequest();
