After running a JavaFX 2.0 application the following is displayed in the console:


Exception in thread "main" java.lang.NoClassDefFoundError: javafx/application/application

The NoClassDefFoundError occurs on this line below:

    Launcher.launch(Lifecycle.class, null);

This problem did not occur with an earlier build of JavaFX 2 (build 13). In the manifest jfxrt.jar is included in the class-path property, and the required file does contain the required class file. If the file wasn't referenced then a different error would be occuring. I have noticed that the size of jfxrt.jar in both JavaFX builds (13 and 17) is exactly the same, is that supposed to be the case?
