AbstractCacheStream.performOperationRehashAware() can hang ---------------------------------------------------------- Key: ISPN-9501 URL: https://issues.jboss.org/browse/ISPN-9501 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.4.0.CR1 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 9.4.0.CR3, 9.3.4.Final There are actually 2 different issues: # {{segmentsToProcess}} reuses the {{remoteResults.lostSegments}} {{ConcurrentSmallIntSet}} instance, so when {{remoteResults.lostSegments}} is cleared, {{segmentsToProcess}} is also cleared. # Because of ISPN-9500, {{segmentsToProcess.isEmpty()}} keeps returning {{false}}, so {{performOperationRehashAware()}} keeps waiting for a newer topology.
