Christopher L. Shannon commented on AMQ-7072:
---------------------------------------------
i didn't say we couldn't use JSON-B, that part is fine if we want to move
towards that API for the next major release.
My objection is to replacing the default implementation and dropping Jackson
which has been used for many years, plus it is probably one of the most popular
libraries out there (if not the most popular). If we use JSON-B then you can
simply replace the implementation for your use case and not make everyone else
have to change their setup as the vast majority of users are probably just
happy with Jackson considering there have been no complaints until now.

> The regression we hit at the moment is that activemq enforces TomEE to import
