             Summary: Distributed SFSB cache entries may rehash to different nodes following topology change
                 Key: WFLY-6064
                 URL: https://issues.jboss.org/browse/WFLY-6064
             Project: WildFly
          Issue Type: Bug
          Components: Clustering
    Affects Versions: 10.0.0.CR5
            Reporter: Paul Ferraro
            Assignee: Paul Ferraro


A distributed SFSB is stored in 2 cache entries, one mapping the bean ID to a serialization group ID, and another mapping the group ID to a map of bean instances.
We ensure that both cache entries will hash to the local node, but following a topology change, these entries could get re-mapped to different nodes.
If we made the group ID = the bean Id of the first bean in the group, this solves the problem for 90% of use cases.
