Sergey Beryozkin commented on CXF-5970:
---------------------------------------
I added a 'providerComparator' property which can be used to do a custom sort
of custom readers or writers, such comparator, if set, has to accept Objects
and then cast internally. For now it would work for sorting MBR/MBW but in the
future may be for sorting filters too.
Using this comparator would most likely lead to a non-compliant runtime
behaviour but I agree that some 3rd party providers can 'mislead' the runtime
they can support a given type and then fail thus not giving a chance to some
other custom provider. So it should only be used when absolutely needed :-)
Cheers, 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().
