| Can't discover UML model from KDM model: exception [message #1479577] |

I have discovered a KDM model from my Android project. This works. But discovering an UML model from this is not possible. I get following error message:
Cannot set feature uml!InterfaceRealization.contract to value org.eclipse.emf.ecore.impl.DynamicEObjectImpl@549e7f73 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@13d2db93 (name: Class) (instanceClassName: null) (abstract: false, interface: false)) (org.eclipse.modisco.kdm.uml2converter_0.12.1.201408191633)

I get following error message:

- Are you also using an Eclipse install Windows 64 bits (if you used the provided plugin as Jar) with corresponding MoDisco and ATL versions? If you use Luna, Kepler could be tested too to check.
I have Windows x64 and I have just installed MoDisco modelling components on my x64 Eclipse Luna through the "Install New Software..." option. Haven't tested on Kepler yet...

- What is the size of the input Java model? In case it is relatively big, sufficient memory should be allocated when launching Eclipse.
Actually I don't know the size. The project itself is rather small, but there are also automatically generated classes and a dependency on another project. I don't know if these components are considered, too.

- Is there a log file that is produced containing more precise trace from the ATL VM running the transformation?
I don't know. Where should I look for it?

Maybe you could do a quick test with Kepler, or just rebuild your own version of the plugin from the sources (cf. the initial link I sent you).
Concerning the size of the produced Java model, I was referring to the size of the corresponding XMI file. Anyway, if your project is rather small then it should not be so big I guess.
Could you check that you don't have a log file located at the same path than the input Java model?
