[ https://issues.jboss.org/browse/ISPN-4092?page=com.atlassian.jira.plugin.... ] Eric Bonnot commented on ISPN-4092: ----------------------------------- The modification of those two functions in the class org.infinispan.notifications.cachemanagerlistener.event.EventImpl doesn't work : there is now a test to check if the lists are null or not, and if they are a new list is created, but the new list is never affected or returned. Should it be : @Override public List<Address> getNewMembers() { if(newMembers == null){ this.newMembers = InfinispanCollections.emptyList(); } return this.newMembers; } and : @Override public List<Address> getOldMembers() { if(oldMembers == null){ this.oldMembers = InfinispanCollections.emptyList(); } return this.oldMembers; } -- This message is automatically generated by JIRA.
