[jboss-jira] [JBoss JIRA] (WFLY-6064) Distributed SFSB cache entries may rehash to different nodes following topology change

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.
