   Hi, @lhotari there is a test failure in [Pulsar CI / CI - Unit - Pulsar 
Client 
(pull_request)](https://github.com/apache/pulsar/actions/runs/17453872406/job/49565356595?pr=24698),
 I think the problem is `TopicListWatcher.connectionFailed()` method doesn't 
have a dealineTime or maxRetryCount. If PulsarClient connection is closed, 
`watcherFuture` will never complete.
   
https://github.com/apache/pulsar/blob/2e6a8eb1f200ca687064058a101963713b896fe2/pulsar-client/src/main/java/org/apache/pulsar/client/impl/TopicListWatcher.java#L92-L107
   
   I read the source code of ConsumerImpl.connectionFailed() method, and I 
prepare to use `this.lookupDeadline = System.currentTimeMillis() + 
client.getConfiguration().getLookupTimeoutMs();` as `watcherFuture`'s deadline. 
I think it is reasonable, because TopicListWatcher and TopicLookup are kind of 
same things.
