Well, it turns out that jython.jar does contain a "javax/script/ 
ScriptEngineFactory.class" file that conflicts with the JVM's one in  
our case.
The groovy test seems to run if I remove the "jython.jar" from the  
web-app's lib dir in jetty, which is ok as long as I don't need to  
run jython-based tests.

Maybe the developers could look into removing the conflicting classes  
from jython.jar for TM 5.1, if this doesn't break anything else?


Cheers,
