[infinispan-issues] [JBoss JIRA] (ISPN-8226) PutIfAbsent can succeed in scattered cache on non-null entry

PutIfAbsent can succeed in scattered cache on non-null entry ------------------------------------------------------------ Key: ISPN-8226 URL: https://issues.jboss.org/browse/ISPN-8226 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.1.0.Final Reporter: Radim Vansa Assignee: Radim Vansa When the {{putIfAbsent}} is a retry, the value/metadata in RepeatableReadEntry is reset to the first loaded version. However if this command caused a prefetch from remote node after finding {{RemoteMetadata}} locally, the first loaded version is the remote metadata and the value updated by prefetch is reset, despite the prefetched value being already inserted into DC. The command sees {{null}} as cache value and since the seen version matches to the version in DC, the write is allowed.
