CacheRegistry is missing entries (e.g. client mappings) following a merge after a cluster split ----------------------------------------------------------------------------------------------- Key: WFLY-7240 URL: https://issues.jboss.org/browse/WFLY-7240 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 10.0.0.Final, 10.1.0.Final Reporter: Radoslav Husar Assignee: Radoslav Husar Priority: Critical One of the manifestation of the issue: # start 2 nodes with SLSB with TUNNEL transport # start both nodes creating 2 clusters (or partitions) # start ejb client # start GossipRouter and wait for merge # ejb client keeps talking only to known node; never receives a topology update This is because org.wildfly.clustering.server.registry.CacheRegistry#topologyChanged does not handle cluster merges.
