JavaFX 19-ea+11 Crashes

Thu Sep 15 12:25:15 UTC 2022

Hi,

I'm using java 17.0.4 (ubuntu 20.04 default build).
Random crashes also happen with graalvm 22.2 (the logs look different).

It does not crash constantly, they're somewhat rare random crashes.

I can check other versions of java to explore the problem, but in
deployment I have to stick with 17.

By looking at my log (I'm not an expert on this), it seems to be a crash on
the G1 garbage collector thread.

But thanks for the tips, It's something I can try (disable the
optimization).
