Hey folks, Using cas 4.2.2, I am seeing a strange problem that is throwing a Null pointer and causing an "Unable to correctly extract the Initialization Vector or ciphertext." Exception, full exception at the end of the post.
The strange thing is, this only happens when the two instances in the cluster are running, they share a hazelcast ticket registry. If only one instance is running, we don't seem to have this exception. It also only seems to be happening on one handler, not the other, which is weird. Does anyone have any pointers? Thanks, John 2016-11-07 06:50:52,266 ERROR [org.jasig.cas.util.WebflowCipherExecutor] - Unable to correctly extract the Initialization Vector or ciphertext. org.apache.shiro.crypto.CryptoException:
