I think it is probable that this is a hotspot VM problem in the C2 JIT
compiler code.
I've moved your bug report to hotspot :
https://bugs.openjdk.java.net/browse/JDK-8283386
The interesting question isn't about which version of FX used to work.
It is what was the last working version of the JDK.
It looks a bit like a JDK 17 bug from the evidence so far so if
you were running FX 17 on JDK 17 GA you maybe have picked up a later
update release of JDK 17 along with FX 18 ??
Regardless this doesn't look like an FX bug.
But unless you can actually provide a test case, or, by luck the hotspot
folks recognise the issue,
I don't know what can/will happen.

Hi John, all,
Thanks for your detailed reply.
I submitted a bug report with detailed information.
- Run a different Java version
I tried different versions and vendors with the same result.
* OpenJDK 17.0.1
* Zulu 17.0.2
* I wanted to check also JDK18-ea but gradle does not yet support it
- 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
I use no specific setting, all is default.
I have been reading that the -client flag might help in some cases but
unfortunately this flag is no longer taken into account for 64bit JVMS.
Thanks,

Hello,
I take the liberty to ask on the email reflector if there are other
people
with similar problems.
Since updating my application to JavaFX18 I get random fatal crashes.
Unfortunately it is not predictable but after some time the app crashes
with "EXCEPTION_ACCESS_VIOLATION".
The hs_error_pidX reports the following.
--------------- T H R E A D ---------------
Current thread (0x0000016be9c9b410): JavaThread "C2 CompilerThread0"

javafx.scene.control.TableView$5::onChanged

Am I the only one seeing this?
I am not sure if this relates to changing JavaFX 17 to 18 or whether it
makes it just more likely.
It seems to be related to "javafx.scene.control.TableView$5::onChanged"
since all crashes show this line.
Having said that, I cannot provide a test-case since it happens all of a
sudden and sometimes after hours using the application.
I am open to any feedback or input on how to proceed best.
Thanks!
