If you want to use the Oracle runtime you need to pay Oracle. But the code itself is open source and you can instead use the Azul, Amazon, Red Hat, BellSoft, etc.. runtimes.
Finally got to the answer. So it IS paid from one particular vendor. I understand there are free options. But that makes it a mine in a field if you are not knowledgable enough. It went this deep into threading to really get an ack that there is a big red O' mine in there.
And there is one piece that wont run without big red O... :(

That seems like looking for a problem where one does not exist to be honest.
The peer comment regarding RedHat is spot on. Yes you can purchase a Linux distro from RedHat and pay lots of money.
That doesn't mean anyone will argue with a straight face that you can't run Linux for free!
It's the exact same scenario with Java. You could pay Oracle for a Oracle JDK if for some reason you reall want to, but approximately nobody does that.
