When i try to run a FX program there is no window opening, instead there is just a empty java folder popping up in my dock (i'm on mac os). I am currently running the newest version of Eclipse,jdk-17.0.1.jdk from Oracle and javafx-sdk-17.0.1 from Gluon. There is no error in my console, vm arguments are correct 100% and i unchecked the second box. The build path is also correct.

The program is also working 100%, as i had it running perfectly in the past and i didn't change anything bout it. I even asked my prof. for help but he couldn't find the reason for FX not working.

Yall got any ideas whats the problem?

    (a) Can you add minimal code here to reproduce the problem? (b) Does it work when started from a console instead of from Eclipse? I also had some problems with JavaFX in Eclipse some time ago, but did not try it lately. Back then, this helped: https://stackoverflow.com/a/55300492/1639625 – tobias_k Nov 11 '21 at 10:03
  • First try with JavaFX 18-ea+6. There have been some bugs recently. Maybe you were hit by these. – mipa Nov 11 '21 at 10:45
  • Do you have the JavaFX-swt libraries included? If so, Eclipse will automatically check a box marked “Use the -XstartOnFirstThread argument” in the Run configurations pane, under the “Arguments” tab. Uncheck that box. – James_D Nov 11 '21 at 12:21
  • Please provide enough code so others can better understand or reproduce the problem. – Community Nov 12 '21 at 12:12
