As far as I know, it concerns only the Oracle Java APIs.
OpenJDK and OpenJFX are largely independent (besides getting contributions from Oracle).
As general Oracle Java was a bit smarter than the OpenJDK (on Linux), the entire outcries are a storm in a glass of water: it makes a (ill guided) sense to let Oracle be paid for its development effort.
The thing to do, is trying out the OpenJDK, and taking notion of com.sun classes.
You might need to look for new versions of your typical server or framework, that might rely on com.sun.* classes.
