The link that you provided is from May of 2016. AFAIK, Google won that case and the appeals and there are no ongoing appeals: https://en.wikipedia.org/wiki/Oracle_America,_Inc._v._Google....
Oracle really has a way of being a big swinging legal turd, I do believe they would try anything they could. It just seems like they wouldn't wait a year to get it going.
There is still a question on fair use. Google won the jury trial, but the appellate court is ruling in a few months, and that could change everything.
