Kevin,

I don't know anything about JPython, but I'd have a very close look at 
how the classpath for your launcher is set up and especially look for 
entries that are supposed to refer to a project but also contain a "/" 
in the name and hence are referring to something within a project where 
a reference to a project is expected.  You might even try to put a 
breakpoint in the WorkspaceRoot to see what path is being used to get a 
better idea...
