[infinispan-issues] [Red Hat JIRA] (ISPN-11381) AdvancedCache.getGroup(key) may return incomplete results during state transfer

AdvancedCache.getGroup(key) may return incomplete results during state transfer ------------------------------------------------------------------------------- Key: ISPN-11381 URL: https://issues.redhat.com/browse/ISPN-11381 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.4.18.Final, 10.1.2.Final, 11.0.0.Alpha1 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 12.1.0.Final {{AdvancedCache.getGroup(groupKey)}} returns all the keys that belong to a group. If the originator is not an owner, the command is forwarded to the primary owner. If the originator is a primary or a backup owner for the group key, the command is executed locally. During state transfer, a node may be a write owner for the group key but not a read owner. Currently {{GroupingInterceptor}} uses {{LocalizedCacheTopogy.isWriteOwner(groupKey)}} instead of {{isReadOwner(groupKey)}}, so it executes the command on the originator instead of forwarding it to the primary owner.
