The OSGi plugin auto-loading was mentioned briefly on Dec's Dom Blog back in June and I hadn't seen much reference to it since, so I was afraid it wouldn't necessarily make it in. Fortunately, it has: I created a new Update Site with the template from an 8.5.3 server, imported the latest Extension Library, ran the "Sign All" agent, and set the notes.ini parameter to look there. And lo and behold: it properly loads up the extensions from the NSF, so I was finally able to delete the filesystem versions that were previously necessary. This makes managing the Extension Library much smoother and it's one less potential gotcha when I upgrade my dev server first and then want to deploy it - since the Update Site has a replica on both servers, the upgrade is handled with the normal replication process and I don't have to remember to copy any files over from server to server. And the fact that it's an NSF theoretically gives you all kinds of other, more complicated deployment options, like server-based Reader field control or partial replication to control which servers see which plugins if you're so inclined. Very cool - I approve, IBM.
