frankjkelly opened a new issue #7927:
URL: https://github.com/apache/pulsar/issues/7927
**Describe the bug**
While testing Authentication the Java Client keeps retrying a number of
times for approx. 30 seconds even though there is a bad JWT token or a missing
JWT token and the broker is responding with
**To Reproduce**
Steps to reproduce the behavior:
1. Turn on Authentication in the Proxy and the Broker
2. Build a Pulsar Client with no authentication
```
return PulsarClient.builder()
.allowTlsInsecureConnection(false)
.serviceUrl("pulsar://" + SERVER + ":6650")
.build();
```
3. Create a Producer e.g.
```
Producer<byte[]> producer = pulsarClient.newProducer()
.topic(topicBeingRequested)
.create();
```
4. See errors and retries in log file - takes approx 30 seconds for this to
stop
5. Setting ```.maxNumberOfRejectedRequestPerConnection(1)``` on the client
did not improve things
**Expected behavior**
I would expect an AuthN or AuthZ failure to return immediately and not retry
**Screenshots**
The client logs show this repeatedly
