--------------------------------------
Here is a simple patch applied to trunk. I've tested it and it solves my
problem.

> Key: CXF-3670
> URL: https://issues.apache.org/jira/browse/CXF-3670
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.4.1
> Reporter: Mike Youngstrom
>
> We recently upgraded our application from 2.3.x to 2.4.1 and we appear to be
> having trouble similar to that described in CXF-3159.
> In CXF-3159 the fix was to basically force the vm to do more class
> initialization. I wonder if a better fix would be to just modify the
> JSONProvider to more eagarly check for a jettison class in a static
> initializer so that there is less reliance on Classloader implementations to
> find the existence of dependencies like this? I'd be happy to provide a
> patch if that would be useful.
