Setting JavaFX 2 Runtime At Start (And Solving "Unable to read ../rt/" Problem)

If you run "java -jar killer-app.jar" on a machine where JavaFX SDK was installed with a simple "unzip" (like a Mac), you will get the following error:

Unable to read ../rt/lib/jfxrt.jar
Unable to read ../../../../rt/lib/jfxrt.jar
Unable to read ../../sdk/rt/lib/jfxrt.jar
Unable to read ../../../artifacts/sdk/rt/lib/jfxrt.jar

Because the Java FX launcher does not know where to find the runtime, it falls back to the default location.
To solve this problem, just pass the system property: javafx.runtime.path with the JavaFX SDK location at start:

java -Djavafx.runtime.path=[THE UNZIPPED JAVA FX SDK]/rt -jar killer-app.jar


Thank you very much for your hint.
