Review Comment:
   How about this indentation and formatting so that the for loop statement 
block is clearly separated from the for loop iterable.
   
   ```java
           for (String listenerName : props.getProperty(
               KRaftConfigs.CONTROLLER_LISTENER_NAMES_CONFIG).split(",")
           ) {

Review Comment:
   This indentation doesn't look correct. We indent Java code using 4 spaces.
