If you want to execute another JavaFX application in the same JVM you can just create instance of it, manually create Stage and call Application#start()

public void runAnotherApp(Class anotherAppClass) throws Exception {
    Application app2 = anotherAppClass.newInstance(); 
    Stage anotherStage = new Stage();
    app2.start(anotherStage);
}
