InfinispanEmbeddedSessionRepository.findByIndexNameAndIndexValue() fails in distributed cache --------------------------------------------------------------------------------------------- Key: ISPN-12751 URL: https://issues.redhat.com/browse/ISPN-12751 Project: Infinispan Issue Type: Bug Components: Spring Integration Affects Versions: 9.4.21.Final, 11.0.9.Final, 12.0.1.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 12.1.0.Final {{InfinispanEmbeddedSessionRepository.findByIndexNameAndIndexValue()}} uses cache streams, but it uses them through the {{BasicCache}} interface instead of the {{Cache}} interface. This means the stream type is {{Stream}}, not {{CacheStream}}, and method overloads with serializable lambda parameters are not available. Thus {{stream.collect(Collectors.toMap(MapSession::getId, Function.identity()))}} will make the collector non-serializable, and it will only work in local/replicated caches.
