"Convention doesn't trump the law."
No, but the question is whether copyright law is appropriate when dealing with API's, which although are technically "published", their purpose is far more extensive than just a paper representation.
Copyright law concepts was written way back,and just was not designed for this. To be honest this is just another example where the way information is used, distributed and disseminated shows that current copyright law is not fit for purpose.
The only people cheering for this judgement to come down on Oracles side, is the author, Oracle and IP lawyers. That's not a group that any sane person would want to be associated with
