[Geoserver-devel] Unable to create class LengthFunction

Hi all,

It appears that with the "Updated to revision 3431" of geoserver, all
datastores (not only the one listed below) are unavailabe due to the same
error :

sr250k:::serie_rouge ignored - as DataStore sr250k is
broken:java.lang.RuntimeException: Unable to create class LengthFunction
