JAXB support for Jackson is a nice-to-have thing, and supported by
community. So if a patch was submitted, support could be added.
I assume no one has needed support for this particular feature so far
(or, it has been difficult to implement).
Having said that, the main downside seems to be that output is as JSON
String, instead of JSON number. I am not sure how significant this is,
as value can be read back without issues.
List of supported annotations is at
[
http://wiki.fasterxml.com/JacksonJAXBAnnotations]; if an annotation
is not listed, it probably is not supported.
Anything that is listed as support is; but there may be time lag on
things getting added.
For more discussion on specific Jackson support for JAXB annotations,
jackson users mailing list is the best place.
