Sure the new features in 9/10/11 are nice, but the license change is still not good for us.
Oracle just want the money, like you can see what the did with google/android and so many other projects.
I dont see any advantage for us.
Its just makes using Java more complicated (for users and devs), because they must care about licenses.
For me personnaly, java gets in the wrong direction with it.
There are too many alternativs for Java in every section, which are also free (nodeJS, Php, C#, .net-Core, Electron…).
And if you look to Android, they want to bring kotlin in foreground and are using openjdk.
Android is not even full java-8 compatible and will not receive java 9/10/11 features so soon(if at all).
For me another question is:
What happens, when we are still using the newst Oracle JDK (because at the moment, its mostly free, they just charge for some modules right?) and Oracle stops contribution on OpenJDK. And if we would go on with Oracle JDK and later they change the license, so we must charge money for the Oracle JDK. We would not be able to got back, because OpenJDK becomes too much behind the Oracle JDK.
