Well, that upgrade has to wait for Neon then -- we simply cannot take much more churn this low in the project. > 2) jersey-2.25 won't work for a similar reason.

Agreed, Tom's utility approach is probably the most sensible one. I took a very simple stab at that with https://git.opendaylight.org/gerrit/70919. I do belive using this you can eliminate any and all references to jersey in shiro-impl. Regards, Robert
