Web Start no longer working with JavaFX?

Question

As of 7.25 (at least), whenever I create a JavaFX project in Netbeans (using 64-bit Windows JDK and Netbeans), trying to launch it with the JNLP file that Netbeans automatically generates results in the following:
java.lang.NullPointerException

Is there any way around this?

It's the JNLP that Netbeans automatically generates for you when building a JavaFX project. It used to run the jar (in the same directory) just by double-clicking it after creating a project, but no longer does. Anyhow, here it is:
