title: No security protocol defined for listener PLAINTEXT://:TCP
body: <pre><code> Error creating broker listeners from 'PLAINTEXT://:tcp://10.99.149.156:9092': No security protocol defined for listener PLAINTEXT://:TCP
  </code></pre>
  
  <p>This is the full message</p>
  
  <p>This looks like bad configuration. I think it shouldn't be both "plaintext" and "tcp".  Where could this configuration possibly come from?  This Kafka is from <code>wursmeister/kafka</code> Docker image.  This worked until about a week ago.  But I don't know exactly how long ago did it change because Docker doesn't really allow one to keep track of version / has very poor cache management.</p>
