ADDITIONAL SYSTEM INFORMATION :
My configuration: MacOS 13.0.1 (Ventura); IntelliJ Community Edition 2021.2; JDK 15.0.2; JavaFX 15.0.1+1
(Sharing this problem on StackOverflow, another user reported the same problem with: OS X (intel) 13.0.1; JavaFX 19; OpenJDK 19.0.1)

I've been using the same JDK and JavaFX versions for months without this problem. I recently upgraded to Ventura; the problem did not occur before then. Is the error on account of upgrading to Ventura? I don't know.

A DESCRIPTION OF THE PROBLEM :
Displaying a dialog box causes multiple errors to be displayed: "Error: <date> <time> java[1066:41315] +[CATransaction synchronize] called within transaction"


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JavaFX project with the code shown below in 'Source code for an executable test case'
Build
Run the program from within IntelliJ, and click on the 'Process File' button. A FileChooser dialog will be displayed, and multiple error messages shown at the console.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The dialog should be displayed, but with no error messages in the console.

ACTUAL -
The dialog is displayed, but this text is displayed in red in the console.
