Hi, In March 2022 we were experiencing some random crashes after upgrading to JavaFX 18 (see [1]). In the end it didn't have to do with JavaFX but with Java HotSpot. I created a bug report [2] which was later closed as a duplicate of JDK-8275610 (see [3]).
By now (Java18) it should be fixed. Note: I cannot confirm this, since we are still stuck with Java17. Which Java version are you using? Maybe upgrading helps and the issue is related. IF you need to stick with Java17 (not sure if it gets backported or how I can check this) you may want to try disabling C2 optimization. -XX:+TieredCompilation (enable C1) -XX:TieredStopAtLevel=1 (disable C2) I hope this helps, -- Daniel [1] https://mail.openjdk.org/pipermail/openjfx-dev/2022-March/033831.html [2] https://bugs.openjdk.org/browse/JDK-8283386 [3] https://bugs.openjdk.org/browse/JDK-8275610 On Wed, Sep 14, 2022 at 10:58 PM Kevin Rushforth <kevin.rushfo...@oracle.com> wrote: > That looks like a HotSpot crash.
