Subject Re: AMQ 224038 on Last Value Queue
Date Thu, 04 Jul 2019 03:27:19 GMT
There are a couple of tests in the test suite which use both last-value and
non-destructive queue attributes (e.g. in
org.apache.activemq.artemis.tests.integration.amqp.JMSNonDestructiveTest).
These work without issue. I also took the code you pasted and tried to
reproduce the failure, but everything appears to be working as expected.
For what it's worth, I'm testing on the tip of the master branch (i.e.
2.10.0-SNAPSHOT).

Would it be possible for you to provide more details about how to reproduce
this failure? Perhaps some simple modifications to the last-value-queue
example distributed with the broker would suffice.
