Ciao Joachim,
the direct raster rendering path has been committed on trunk only, therefore
it looks rather strange to me that you are able to use it on 2.0.2.
So, yeah, please double check your steps, since I think you have downloaded
trunk's source code.
Aside from that, can you tell us more about what you are trying to do with
regards to geoserver. It might worth investigating this error anyway.
Ciao,
Simone.
