The same file loads without errors in Eclipse Modeling Tools Build id: 20090920-1017

Thanks for the report, Paul. The problem is that the class names contain the invalid character ':' - probably round-tripped from an RDF prefix notation. Needless to say, those class names also wouldn't be valid Java or C++ identifiers, but our code should certainly handle them more gracefully.

Do you mind saying how you exported your UML from EA? I tried several of the formats in EA 11 and TBCME didn't like any of them. I'd like to get as far as you did. And, while I am asking, did you ever get further than this thread left off? Thank you!
