{code}
Running on version 2.5.0_1, it does not show this error. Most likely kafka is
not using jackson-databind at this point in earlier versions, but that is just
my assumption.
I found a related issue in the camel community:
https://issues.apache.org/jira/browse/CAMEL-15752
Deviating from their resolution I do not think it is actually a version
conflict, but the servicemix bundle is just missing the import. By adding this
to the consuming project this import gets added. But ideally this would be
added to the servicemix bundle, so not every consumer of the bundle has to care
about it. What do you think?
Another reported issue similar to the one in the camel community:
