Hello John, this issue occurs very rarely, approximately 1-2 times per month, on systems that run 24/7. However, when it does occur, the JavaFx application gets stuck in an endless loop (--> [logError-JavaFxScene.txt](https://github.com/openjdk/jfx/files/11397119/logError-JavaFxScene.txt)) and cannot recover from it. Currently, I am unable to replicate this phenomenon. I fully agree with you that it's essential to address the problem at its root cause. However, adding an additional check for a null value would at least solve a rare but blocking issue.  ------------- PR Comment: https://git.openjdk.org/jfx/pull/1123#issuecomment-1534664290
