["pdolif (via GitHub)" <gi...@apache.org>]

pdolif opened a new issue, #23690:
URL: https://github.com/apache/pulsar/issues/23690

   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
   
   
   ### Read release policy
   
   - [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.
   
   
   ### Version
   
   Pulsar master
   
   ### Minimal reproduce step
   
   Call `TopicName.get(" ")`.
   
   ### What did you expect to see?
   
   This is a test for the behavior I would expect:
   ```java
   try {
       TopicName.get(" ");
       fail("Should have raised exception");
   } catch (IllegalArgumentException e) {
       // Ok
   }
   ```
   
   When creating a consumer with the topic name only being a whitespace we get:
   
   > java.lang.IllegalArgumentException: topicNames cannot have blank topic
   
   ### What did you see instead?
   
   No exception is thrown.
   
   ### Anything else?
   
   _No response_
   
   ### Are you willing to submit a PR?
   
   - [X] I'm willing to submit a PR!
