Oracle, please get your crap together.

If you really wanted to make an amazing replacement for Java swing, you could have made the scene builder application for javafx not crash every 15 minutes on macOS. Seriously. I can't go more than a half hour without it freezing up and/or having the window disappear, never to open again. I get that it's a complicated program, but it's 10 YEARS OLD. It should have been stable by now.
