Kyrre created QPID-8520:
---------------------------
Summary: ReadPendingException thrown by Broker-J intermittently
Key: QPID-8520
URL: https://issues.apache.org/jira/browse/QPID-8520
Project: Qpid
Issue Type: Bug
Components: Broker-J
Affects Versions: qpid-java-broker-8.0.2
Environment: Broker-J 8.0.2
Spring Boot 3.2.2
Docker Engine v20.10.5
Testcontainers 1.15.1
Reporter: Kyrre
Our project is using the HTTPS management interface, using a REST client.
We've wrapped our qpid instance in a Docker container using testcontainers, and
have a test that sets up and tears down different elements we utilise in our
system with asserts that things are as we expected, all this over HTTPS between
the local machine and the container. This works splendidly, except for the fact
that we see intermittent errors in the test of the type

I am fully aware that this might be a bit too little to go by, but I have tried
in to create a reproducible code snippet, but cannot find a way to make the
error occur in a stable and reproducible way. I am also aware that this might
be caused by a number of other things, but figured thia would be a good start
to try to find out what to do about it.
