Matt Pavlovich commented on AMQ-7072:
-------------------------------------
activemq-partition and activemq-store-leveldb have been removed.
The only place JSON is used is in the DestinationsViewFilter.
I think we should localize the JSON to a AMQJson to be explicit for the filter
request being read and model being generated out. This would allow us to drop
Jackson and not require JSON-B at all
> ActiveMQ shouldn't import jackson but use JSON-B instead of jackson to
> support impl switch

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

> spec is out and implemented by both I guess it can be the way to solve that
