[GitHub] [pulsar] fmiguelez opened a new issue #8922: Infinite reconnections (with error) when authentication fails on Java client
fmiguelez opened a new issue #8922:
URL: https://github.com/apache/pulsar/issues/8922
**Describe the bug**
Connection layer of Java client keeps on trying (and failing to) reconnect to broker when access token used to authenticate expires.
It seems that connection pool handles connections transparently in the background even if all consumers/readers are closed.
To reproduce it create a consumer with a Pulsar with security (JWT auth) enabled. Use a short-lived token (a few minutes). Once token has expired now and then connection times out and pool tries to reconnect it (even if no consumers/readers are present). Then we will see periodically in log these entries:

**To Reproduce**
Enable JWT based authentication and issue a short-lived token. Publish and consume some messages using that token. Wait a few minutes until token expires.
**Expected behavior**
Connection pool should not try to reconnect (or at least retry only a few times) when authentication fails.
**Screenshots**
**Desktop (please complete the following information):**
- Windows (Docker Desktop)

Any chance this is related to https://github.com/apache/pulsar/issues/7927 - at least insofar as the reconnections bit?
