This is a relative URI, not an absolute one, so relative references 
within that resource will not likely be handled correctly.  It would be 
good to see the actual value that you're using.

I don't know anything about uma schemes.   I guess human readability 
wasn't a concern...

That method uses just the fragment, i.e., "_GgH6wOn8EdyMKb-pMuCr4g".  I 
would imagine that even if the proxy fails to resolve (you can cast to 
InternalEObject and use eProxyURI to see the URI of the proxy that's 
failing to resolve) you'd still have a resource with URI 
"uma://_wTuT0MmrEdyxNoaGNtevxw".  If you called getErrors on that 
resource, it will likely indicate why it failed to load.  It sounds like 
you might well need to be hooking up some special support to handle uma: 
scheme, but that's an probably EPF question I can't answer...

Well, you mustn't have the dependencies right.

Try using "Required Plug-ins" instead.
