I do not know what the above means. Please note, that you should register
just one ContextResolver<ObjectMapper> instance, as Jackson will use
only the first one
if more that one such provider is found. To create different object
mappers, you should
use the getContext method bellow.

right, the above should ensure, the enclosing element is omitted.

Correct. The fixed version should already be available there.
