Oliver Gondža commented on AMQ-8265:
------------------------------------
I can and I will. It is just we do not have a reproducer and run into this
rarely, so it will be hard to tell whether it improved or not. Can you point me
to those improvements that feels relevant to you? I run through release notes
and related code changes but found nothing. Thanks!
