---------------------------------------

Hi Romain,
Can you give me an example please of where the factory loses the expected 
priority ? Ultimately the runtime must guarantee the providers are sorted 
correctly,

Thanks, Sergey

> Actually the task can be rephrase saying rework 
> org.apache.cxf.jaxrs.provider.ProviderFactory#*Comparators
> Current implementations don't seem to have an absolute order which means 
> sorting is not as deterministic as it should be under java >= 7.
> Other point is as a user you set a List of providers (you probably already 
> sorted if important) so you want to ensure *your* order is respected at 
> runtime (ie 
> org.apache.cxf.jaxrs.provider.ProviderFactory#message[Readers|Writers] 
> respect it).
> If you think this sorting is important maybe introducing in 
> org.apache.cxf.jaxrs.AbstractJAXRSFactoryBean and 
> org.apache.cxf.jaxrs.provider.ProviderFactory a boolean sortProviders can be 
> enough to prevent calling sortXXX().
