Yes, it works fine.
I downloaded the .jar installer file and just ran it with "java -jar"
It just creates a directory with the files, which you can then run with:
java -Xmx128M -jar FreeCol.jarThat's it. There's not much to show with regards to screenshot because it goes full screen. It'll look like any other platform, unless you want to bring an OS/2 window in front just to "prove" it.
