Fedora Silverblue is immutable, container-based and all that Fedora users are talking about https://docs.fedoraproject.org/en-US/fedora-silverblue/
OpenJDK not offering installers for Windows users is a very bad thing. I can do the manual install, but I can't think of another programming language that makes you do this.
I spent considerable time futzing with OpenJDK 12 in Windows, going back to Oracle's JDK 8, and trying to get JavaFX 12 to work. I messed with Netbeans 8.2, then 11, then back to 8.2. That the JDK "story" after Version 8 is so shaky, it's a problem.
