Work Description: jbertram opened a new pull request #3243:
URL: https://github.com/apache/activemq-artemis/pull/3243
I couldn't reproduce this with a test, but static code analysis led me
to this solution which is similar to the fix done for ARTEMIS-2592 via
e397a177967bcf431b9fa82463a61b152ba82fb0.
