I'm filing this mostly as help for the next maintainer (maybe myself in the future).

Upstream migrated to Github: https://github.com/CSPforJAVA/jcsp

1.1.10 release should be compatible with what is in the archive,
however upstream switched their Java package name from "org.jcsp" to "jcsp",
so probably new patches will be needed for some dependencies.

I don't have time now for work on this, that's why this is wishlist.
