Description

When in Zookeeper mode, if a port the broker should listen to is already bound

the KafkaException: Socket server failed to bind to localhost:9092: Address already in use.

is thrown but the Broker continues to startup .

It correctly shuts down when in KRaft mode.

Easy to reproduce when in Zookeper mode with server.config set to listen to localhost only
listeners=PLAINTEXT://localhost:9092
