As discussed on issue #35628, at some point the host property accepted multiple comma-separated hosts. However, this was not intended, and for better clarification, it was decided to implement a clearer error message for this situation.
This PR adds an extra check in
org.springframework.boot.autoconfigure.amqp.RabbitProperties#determineAddresses
for commas in the host property, throwing anInvalidConfigurationPropertyValueException
if any is found.
