Jean-Baptiste Onofré commented on SM-4641:
------------------------------------------
I already fixed that in Decanter (decanter does't use the SMX bundle, it embeds
kafka client as private package):
[https://github.com/apache/karaf-decanter/pull/225]
I gonna fix that in SMX bundles as well.

> 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:

> 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. In OSGI this import is a must. What do you think?
> Another reported issue similar to the one in the camel community:
