I can understand porting C# code to Java code, but what I don't understand and what the article doesn't explain is how they handled their dependencies, i.e. System.* libraries.

They clearly didn't port the CLR libraries to the JVM, so they must have modified their code to work with Java libraries, e.g. Swing, etc. To me, it seems like this would be the bulk of the work, not language translation from Java to C#.

Good point - its not the language translation per-se but the ecosystem surrounding it unless there's is one of those projects where they hand-coded everything and used no external libraries at all. I doubt it very much though.
