Mandy,

Thanks for the help. 

I guess I would suggest that either jmod should not be included in the 
legacy image, or it should have a more friendly error if there is no 
system module image available.  There should also be a way for code to 
query the system to determine if this is a legacy image or a module 
image, so that tests (for example) can adapt their behavior accordingly.
