Looking at the stack trace below, it seems that either there is a  
URIResolverImpl
that is not registered with the EMF ResourceSet, or a resource  
pattern that will
match the comptype:.. URL has not been registered. This is then  
causing a fallback
to the JDK's URL definition and I would be sure that the comptype:  
protocol is not
registered by default :)

Devang, what do you think is missing?

Possibly a knock-on effect from the exception thrown - looks like
there's no error recovery here.
