We have it casified at Lafayette. I'd have to look up my notes, but we did have some trouble after the install. I believe it was in web.XML.in, and it was our own fault. Because of the way we ported the changes forward. We clobbered some of the touch logic. Once we found that and fixed it, it works perfectly. We're on 8.6.0 patch 3, and we came from 8.0.6.
Let me know if you'd like more details.
