Hi Ivan,

This is because Furnace proxies the objects to avoid ClassCastExceptions. This shouldn't present a problem though. Are your addon dependencies correctly configured? I haven't seen your project yet, but if you could reproduce this error in a test that would be great.

I dug as deep as the AbstractFaceted::safeGetFacet(Class<F> type) method. What it does is: it searches all the installed facets and it checks whether the expected one is among them by calling type.isInstance(facet).

So I expect the type to be com.sap.cloud.forge.SapHanaCloudFacet, but it is actually something like org.jboss.forge.addon.facets.AbstractFacet_$$_javassist_904cc85e-43dd-404a-846c-ed4709d14dea. Eventually, the isInstance method returns false.
