When running BrickBreaker.jar from the latest deploy scrum build, I get the following exception if jfxrt.jar cannot be found.

The line number is preceded by a comment indicating that a standalone app should not get there. Apparently, it somehow did get there.

Note that the latest 2.1 master build correctly displays a dialog with a message indicating that JavaFX is not installed.
