Looks very similar to this issue: https://issues.jboss.org/browse/ISPN-6366
However, not sure if it's a duplicate as our configuration is nothing like that mentioned & the line number in the stack is one off.
Not sure what version the other issue was reported against though (and the line number in the stack on the mentioned issue is a null check in 8.2.2 final).


Configuration for the cache with this problem is included below:
