0.37.0.pre2

---

Fixes #2

This is my first patch for JRuby, so any feedback would be appreciated. The specs do not run (Ill file a separate issue) but I am able to successfully start up & run the contents of a `Procfile`.

I based this patch on [launchys JRuby support](https://github.com/copiousfreetime/launchy/pull/10) and I too confirmed these changes did not break 1.8.7, 1.9.2 or 1.9.3.
