    Description

      Persistent priority messages do not get dispatched correctly.
      Messages with higher priority fail to be dispatched on top of default messages once a backlog on the queue accumulates.
      This happens even while the cursor holds all messages in memory, so its not related to paging in messages from the store.Broker config uses|activemq.xml|

      <policyEntry queue="Prioritized.Queue" prioritizedMessages="true" queuePrefetch="1" maxPageSize="1000">
      <deadLetterStrategy>
      <sharedDeadLetterStrategy processExpired="false" />
      </deadLetterStrategy>
      </policyEntry>

      A similar but not exactly same behavior is observed when switching to vmQueueCursor.

          Bug - A problem that impairs or prevents the functions of the product. ENTMQ-872 Non-persistent priority messages not dispatched according to their priority

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
