[infinispan-issues] [JBoss JIRA] (ISPN-7051) Intermittent RpcException during PUTs and GETs when topology changes

[Dan Berindei (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-7051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13301737#comment-13301737 ] 

Dan Berindei commented on ISPN-7051:
------------------------------------

IMO if one of the owners in the read CH doesn't have the value, it's OK to return {{null}}, even if another owner later turns out to have the value. If a {{cache.put(key, value)}} is in progress, a {{cache.get(key)}} operation is allowed to return either the new value or the old one.

If B returned {{null}} because it has a newer topology in which it's no longer an owner, then we have a bug, but based on [~rvansa]'s description that's not the case.

> The commit https://github.com/infinispan/infinispan/commit/6ae4e2e7707285287ef753661943a5623d8eb271 seems to be introducing intermittent errors during gets and puts under topology changes
