[jira] [Updated] (ARTEMIS-5183) STOMP noLocal filter ignores legitimate messages
[ https://issues.apache.org/jira/browse/ARTEMIS-5183?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Justin Bertram updated ARTEMIS-5183:
------------------------------------
Summary: STOMP noLocal filter ignores legitimate messages (was: Stomp consumer with noLocal can't receive messages from producer not using noLocal)
> STOMP noLocal filter ignores legitimate messages
> ------------------------------------------------
>
> Key: ARTEMIS-5183
> URL: https://issues.apache.org/jira/browse/ARTEMIS-5183
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: STOMP
> Affects Versions: 2.37.0
> Reporter: Tommy Lindgren
> Assignee: Justin Bertram
> Priority: Major
>
> If client 1 subscribes with {{noLocal=true}} to {{/topic/example}} and client 2 sends messages to {{/topic/example}} but doesn't use {{noLocal}}, then client 1 won't see the messages from client 2.
> If {{noLocal=true}}, {{StompConnect.java}} will add {{\__AMQ_CID<>xxx}} to the selector. However, the {{\__AMQ_CID}} header is only added to the message if {{noLocal}} is enabled, so the selector won't match anything (presumably because <> never matches NULL).
> Untested potential patch:
> {noformat}
