The fix is great but please change how the AMFGraphPlugin is registered to only parse root files. This way we depend on declarative configuration, not imperative code logic

This is optional, the try-catch makes more sense as a fix

@arielmirra can't we change the context jsonld parser to return something a bit more meaningfull and avoid throwing the exception ?

@nschejtman what will happen once we implement remote context parsing ? This test will break. Exception caching is just a patch for me
