Find that in writing. Everything I read says jdk 8 is the last free Oracle jdk.
"This is as in many other projects, except it seems that releases of the LTS version, dubbed to be Oracle JDK, will no longer be free. This means that companies looking to stay on a specific version for more than six months would need to get updates from a commercial operator or apply patches from later free OpenJDK versions manually."
Firstly, it is not clear that there will be an Oracle JDK that is $free to download. Despite my best attempts, I could not get 100% clarity on this point, but see also this tweet.
The only change is that free security patches will now be limited to six months after a release.
