Update:  I have been able to reproduce this bug.

The root cause is that two versions of the same plugin policy are being use at the same time in the same gateway.  There shouldn't be any issue/problem with that, and the fact that an error occurs in this scenario is simply a bug in how we are caching the policy configuration info.

Should be an easy fix and will be included in 1.1.9.Final.
