[news.eclipse.modeling.mdt.uml2] Re: Upgrade from UML2-2.2.1 to UML2-3.0

["James Bruck" <jbruck@xxxxxxxxxx>]

Although I haven't verified this, you can try simply registering the older 
nsURI against the latest UMLPackage.eINSTANCE in the package registry.  The 
automatic up-conversion to the latest version of UML should then occurr 
automatically.
Try something like 
resourceSet.getPackageRegistry().put(UML212UMLResource.UML_METAMODEL_NS_URI, 
UMLPackage.eINSTANCE);

In general, if you are having problems in "stand alone" mode, you can look 
at the extensions in the  MANIFEST.MF in org.eclipse.uml2.uml and try to 
mimic the extension point registrations that happen there.

Simply changing the nsURI in the file itself will work "most" of the time 
since little has changed between the 2.1.0 and 3.0.0 opensource versions 
however this is not recommended and could lead to problems.

The following describes what has changed:
