Question about fatal JavaFX crashes

[John Hendrikx]

I haven't seen this one; the code in TableView in onChanged hasn't had 
any updates 6 years.

I have my doubts this is a JavaFX problem as it seems the Compiler is 
crashing here in a piece of native code.  It's possible this problem is 
only occuring on systems where the compiler decides it needs to compile 
(or recompile) this method, so at a minimum you'd need to make use of 
TableView in a way to hits that code path often enough to trigger 
compilation.

Oracle provides some documentation on how to deal with what looks like a 
compiler bug, please read here:

https://docs.oracle.com/en/java/javase/17/troubleshoot/troubleshoot-system-crashes.html

Further, I think you should report this problem with as much details as 
possible on bugs.openjdk.java.net -- you can look for similar bugs to 
see what kind of detail and settings would be helpful to debug this.

Other things you could try to solve it yourself:

- Run a different Java version
- Try switching to a different GC
- Use different VM options (are you using anything special?)
- Anything else that is not often used, non-standard or experimental, 
try going to a more common setup
