In the consumerGroupCommand tool we return an illegalArgumentException if the type is unknown so I thought maybe it would make sense to do that here as well. To ignore it should parse return null? If it returns null I was worried about NullPointerExceptions wherever this method is used. If I wanted to return UNKNOWN type like how it is on the client side, we would have to add that to the enum on the server side. Is there some obvious way to do this that I'm missing? -- This is an automated message from the Apache Git Service.
