Previously, the synthetic method for containsAll in Baz had the parameter type com.example.Baz (without the <?>, meaning it is a raw type). There are two problems with that:
raw types trigger a warning from javac by default
in this case, it causes the output not to compile (because the implicit override is not correct - the types aren't compatible)
Based on an example I found while investigating cf-691.
