[infinispan-issues] [JBoss JIRA] (ISPN-10365) PreferAvailabilityStrategy assertion failure

PreferAvailabilityStrategy assertion failure -------------------------------------------- Key: ISPN-10365 URL: https://issues.jboss.org/browse/ISPN-10365 Project: Infinispan Issue Type: Bug Components: Core, Test Suite - Core Affects Versions: 10.0.0.Beta3, 9.4.15.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Labels: testsuite_stability Fix For: 10.0.0.Beta4, 9.4.16.Final This scenario happens unintentionally in {{RebalancePolicyJmxTest}}, because the test waits for the default cache to finish rebalancing before killing the coordinator but doesn't care about the {{CONFIG}} cache: * A and B are running, rebalancing is disabled, then C and D join * Re-enable rebalance, but stop B and A before the rebalance is done * C sees the finished rebalance, D sees the READ_OLD phase * C becomes coordinator and should recover with C's topology, but instead has an assertion failure and doesn't install a stable topology {noformat} 16:48:48,454 TRACE
