StringJsonMessageConverter doesn't work with List<Message<PO>>

[realcbb]

StringJsonMessageConverter works well with Message<PO> as method parameter when using @KafkaListener, but doesn't work with List<Message<PO>> in batch listener mode. Already set factory.setMessageConverter(new BatchMessagingMessageConverter(jsonMessageConverter));.
It seems that the listener does not using StringJsonMessageConverter to convert each record when the message parameter isMessageList.

Confirmed.

Do you really need the complete messages?

This works...

@KafkaListener(...)
public void listen1(List<Foo> foos, @Header(KafkaHeaders.RECEIVED_TOPIC) List<String> topics,
		@Header(KafkaHeaders.RECEIVED_PARTITION_ID) List<Integer> partitions) {
    ...
}
