Well, Google itself heavily uses Oracle's OpenJDK internally (as do Apple, Amazon, Netflix, Facebook, Microsoft, Twitter and many, many others), and have even forked it, contributed to it, and spoke about it at a conference at the Oracle campus [1] -- all at the very height of the lawsuit -- so they clearly aren't concerned. Whatever you think of that lawsuit, the circumstances behind it were so extreme (one company copies over 10KLOC from another in order to directly compete with it in a very lucrative market) that nothing like that had never happened before nor has happened since in the software industry.

> and by their JDK licencing scheme change

The JDK licensing change was that Oracle changed the JDK from part-commercial part-open to 100% open for the first time in Java's history. On the commercial side, the change was from part-upfront, part-subscription to just subscription, which cut the price for customers by a factor of 5, I think.

What's important to remember about Java is that it's huge, and many companies make money off of it, and so companies have an interest creating FUD over Oracle's involvement. I can't speak for other parts of the company, but there's near consensus among Java users that Oracle has been a better steward of Java than Sun, both in terms of technical investment as well as licensing.
