[infinispan-issues] [JBoss JIRA] (ISPN-11981) Stale immortal entry metadata

Stale immortal entry metadata ----------------------------- Key: ISPN-11981 URL: https://issues.redhat.com/browse/ISPN-11981 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 11.0.0.CR1, 10.1.8.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 11.0.2.Final When an entry is updated, {{InternalEntryFactoryImpl}} tries to reuse the existing {{InternalCacheEntry}} instance instead of creating a new one. The condition is that both the new and the old entry have the same implementation implementation: immortal, immortal w/ external metadata, transient, transient w/ metadata etc. Because {{MetadataImmortalCacheEntry}} extends {{ImmortalCacheEntry}}, that logic is broken: when an immortal entry with external metadata is replaced with a new entry without external metadata, the external metadata is not removed. This impacts the anchored keys module, which I am changing to store the key location in the metadata (currently it is stored as a value, and it is broken with BINARY/OFF_HEAP storage). When a node leaves and an entry located on the leaver is updated, the key is written on the newest joiner. The joiner already has a local entry with {{RemoteMetadata}}, and is trying to write a value without any metadata.
