Sergey Beryozkin commented on CXF-6746:
---------------------------------------
I've updated the Jackson version, see
http://git-wip-us.apache.org/repos/asf/cxf/commit/8f98be8e
and CXF tests run OK.
What is likely happening is that you have some beans that both Jettison and
Jackson can handle, example, it is XMLRootElement annotated beans. CXF 3.1.x is
more compliant in the way it selects providers. Jackson is a wildcard provider,
it has wildcard Produces/Consumes, while the default CXF Jettision based
provider is more specific in its Produces/Consumes - hence when both providers
are loaded and both can handle the given data Jettison will win.
Exclude Jettison and it will work as expected, if not - please create a Maven
based test case

> I observe some poblem during using JacksonJsonProvider.
> Firstly we have CXF v. 2.7.15 and using default Jettison provider.
> From some reasons (Jettison convert POJO String field to "json-number" if
> it's possible,
> http://stackoverflow.com/questions/22379082/jettison-string-returned-as-integer-when-marshalling)
> we decide change provider on JacksonJsonProvider.
> I change Jettison on JacksonJsonProvider v. 2.6.4 and observe some problem,
> application frozen after some time if we active use new provider.
> Because CXF v. 2.7.15 is too older, we decide change CXF version on latest
> 3.1.4
> After change version of CXF I observe that CXF use default Jettison proveder
> insted of JacksonJsonProvider despite the fact that in I configurate CXF for
> using JacksonJsonProvider. If I only change version of JacksonJsonProvider on
> 2.0.0 all works fine.
> Result:
> *CXF v.2.7.15 with Jackson v.2.6.4 work, but have some bug (don't descride
> them because v.2.7.15 is too old).*
> *CXF v.3.1.4 with Jackson v.2.6.4 doesn't work, CXF use default Jettison.*
> *CXF v.3.1.4 with Jackson v.2.0.0 work fine.*
> If you need some additional information please write here, thank you.
