how to fix Java WebStart on MacOSX 10.5.7

I don't know when this broke - maybe around the time Safari 4 was released? Anyway, Java WebStart stopped working. Downloading a .jnlp file and doubleclicking it brought up an editor (Dashcode) rather than the application launched via Java WebStart. I tried using Spotlight to find "Java WebStart" so I could manually launch the app. But nothing was found. WTF?

Murphy: 1, D'Arcy: 1

After what felt like a very long weekend of debugging jGenerator, I finally figured out what was going wrong, and how to fix it. It didn't make sense at all, which is why I didn't pursue that line of investigation earlier. The library worked fine before. It hadn't changed. Then it didn't work. I was figuring that meant something outside of the library had changed, and had borked something used by jGenerator....
