Re: [Resteasy-developers] JAXB and JSON Provider Configuration

[Bill B. <bb...@re...>]

I'm fine with that.

The JSON JAXBContexts existed as I thought users might want to use it 
outside of Readers/Writers.

FYI, I have a huge serious refactoring coming.  I don't think it will 
effect providers, but most of the codebase is affected.

Reason?  Well, 0.10 changes a lot.  Specifically:

* how encoding works
* No more Path.limited
* Regular expression in @Paths
* other minor API changes

I've been working on it for a week now (mostly), still not done :(
