Your original statement was you can't BUILD an implementation without getting Oracle's blessing. Now you've switched to saying you can't CERTIFY which is a different claim.

I understand that you are trying to play semantics here, but in this case it doesn't work.

You can't BUILD an implementation of Java, because "Java" is defined by "passes the Java conformance tests".

You can build "something", but it won't be Java, so don't call it Java. Even Google understood that.
