My instance of it has been quietly sat on a CentOS 6 (i.e. PHP 5.3.3 with backported security patches) box that I'm now trying to migrate away to, so as a result have needed to port JILS over to working on PHP7 So far, that's largely been hacked together in place (will attach patches), but it's almost certainly worth the effort of bringing the codebase up to date for easier deployment onto more modern platforms.
