Inprevious releases of JBoss EAP 6, any management operations that listed messages would incorrectly list paged messages before previously sent messages.
Other possible out of order issues were also identified in cases after redeliveries.
This issue was fixed by rectifying the order where the Iterator takes messages before sending them to management operations.
+++ This bug was initially created as a clone of Bug #1088601 +++
Should be fixed by upgrade https://bugzilla.redhat.com/show_bug.cgi?id=1064596 for DR2
Verified using test QueueImplTest in EAP 6.3.0.ER7. Thanks!
