Mark Mindenhall commented on CAMEL-9026:
----------------------------------------
[~ancosen], [~tdiesler], I saw discussion of this go by in camel-dev, and have
a couple of questions.
First, I'm concerned that this might have somehow been caused by the patch I
submitted for CAMEL-8790. However, there's a test in
{{org.apache.camel.component.kafka.KafkaProducerFullTest}} that uses
{{kafka.serializer.StringEncoder}}, and that test passes without this patch.
So I'm wondering if you can provide more details about the route configuration
that resulted in the exception?
Second, the patch for CAMEL-8790 was backported to the 2.15.x branch...can this
be backported as well? It should merge cleanly, and if I was the cause, either
this patch needs to be merged or my patch reverted from 2.15.x to avoid
breaking things for existing 2.15.x users.
Thanks!
