[infinispan-issues] [JBoss JIRA] (ISPN-9220) Client listeners are sometimes re-registered twice after infinispan-server restart

Client listeners are sometimes re-registered twice after infinispan-server restart ---------------------------------------------------------------------------------- Key: ISPN-9220 URL: https://issues.jboss.org/browse/ISPN-9220 Project: Infinispan Issue Type: Bug Components: Hot Rod Affects Versions: 9.2.1.Final Reporter: Marek Posolda Labels: redhat-summit-18 During test of summit, we saw some issue with client listeners. Setup was this: - Every site had one hotrod client (RHSSO), which used infinispan of version 8.2.8.Final and one infinispan-server, which I think was version 9.2.1.Final - Client (RH-SSO) had some client listener registered against remoteCache - After restart of infinispan-server, the RH-SSO was able to re-connect to it and CRUD the items to the remoteCache. But previously registered clientListeners were lost. Note that setup demo used just 1 infinispan-server on every site, so there were not any topology changes (no possibility of re-balance client listener to other node). I've tried to do simple reproducer for the scenario above and verified that with client 8.2.8.Final and server 9.2.1.Final, the client listener is not automatically re-registered after restart. BUT after upgrade client to 9.2.1.Final, re-registration worked fine and client listener was re-registered automatically. This is important as from long term perspective, we are upgrading to infinispan 9 on RH-SSO side. But I had the opposite issue, that sometimes the client listener is registered twice. See steps to reproduce for the details.
