The permissive license here does not matter, since Oracle did not comply with the extremely liberal terms of the license.
The implementation of Java and the implementation of the AWS API does not matter, since the Oracle-Google suit is (at this point) strictly over the structure sequence and organization of the APIs. How the code implementing the API came to be is completely and wholly irrelevant to the suit at hand.
Not that it matters (as explained above), but you're also wrong that google took java and executed 's/java/GoogleJava/g'. They re-implemented the entire API in dispute by hand, the only portion they copied from Oracle's implementation was the API.
