Hi mdt uml2 folks,

I've been working in profile transformations and would like to reference
both a custom metamodel (instead of UML2) and its metaclasses. So, I
converted the model to a metamodel selecting UML Editor -> Convert to ->
Metamodel and all the metaclasses automatically received a <<metaclass>>
stereotype.

But when i call the method createExtension() and pass as first argument a
metaclass (of type Class), an IllegalArgumentException is thrown:

Exception in thread "main" java.lang.IllegalArgumentException:
org.eclipse.uml2.uml.internal.impl.ClassImpl@1094d48 (name: PrimitiveType,
visibility: <unset>) (isLeaf: false, isAbstract: true) (isActive: false)

at profilegenerator.ProfileGenerator.main(ProfileGenerator.java :69)

I called the metaclass.isMetaclass() method to confirm that metaclass is
really a metaclass and figured out that it prints 'false', indicating that
the metaclass argument passed to createExtension() is not in fact a real
metaclass. So, i would like to know what i have to do make the method
isMetaclass() prints 'true'.

Class::isMetaclass() will return true if the 'metaclass' stereotype from the
standard profile is applied to the class.
