Hi We have a bigger PR https://github.com/apache/camel/pull/21644
That will be merged soon. Its part of the work to support both jackson2 and 3 a bit at the same time. So we can use jackson 3 in SB4, and then for a while jackson2 may be needed for some 3rd party libraries that have not yet migrated to jackson 3. -- Claus Ibsen
