Why can Scene's only be constructed on the UI thread?

[Richard Bair]

Hi,

Actually I don’t know of any reason why Window and Scene cannot be created and initialized on any thread. Each of these has a peer, and the *peer* we can’t update except on the right thread (or with care, these are OS specific restrictions or issues). But I don’t see any reason why the Java side cannot be initialized on any background thread. And in fact, that was always my intent for exactly these reasons, having experienced all this pain in Swing before firsthand.

Its just work that needs to be done, contributions welcome :-)

I had heard years ago jre 8 was going to address this via 2 drawing threads and modularity but jigsaw was delayed and not sure what happened to the 2 drawing thread idea. I really wish we could instantiate windows in memory and when needed draw them. The user experience and perception of java would be so much better for the client side. If someone on the java client side knows how to do this I would love to try it to verify it.
