I am trying to convert to Java14. Project uses JavaFX and works fine on Java 13.0.2. I have updated JAVA_HOME and the PATH, netbeans.conf, the Java Platform (now JDK 14 default), source format is JDK 14. I have uninstalled nb-javac (I assume this is done via Plugins manager). I'm using JavaFX 14. Project compiles and builds with no problem. Run does nothing. It appears a critical error has occurred silently.
A tiny test project compiles and builds ok. I note subtle differences between the 'Properties' pop-up for the test project (a Profile option, a runtime platform option) and the failing project.
If I change the Source format back to 13 and re-install nb-javac my project runs ok (obviously, the test project does not!)
