As per my understading of the efforts required (I hope to be wrong here),
this is ideal but unrealistic for CXF. We either
start build some foundation (following other projects), or embark on
transforming everything to named modules (and we will be
affected by all our dependecies anyway, there is nothing we can do about
it). I see the first option doable, CXF won't
able to embrace the migration at once untill all and every dependency we
use does the same. This might happen eventually
but not any time soon for sure :-(


Why not keeping it unamed then? There are very few adherence on cxf except
in integrations, no?



RMB> This is my first point. Once named and fully migrated you hit both
issue: not default classloader and visibility
RMB> change. First is surely workaround-able but last impacts users so
better to let people migrate on java 9...only
RMB> once and not N times cause CXF didnt embrace it at once. This is my
big concern.

 RMB>> yep

  RMB>>> Or the worst since you dont expose the "api" but all the classes
and breaks SPI since service loader loading is different in named modules,
no?

RMB>    RMB>>> Hi Romain,

RMB>    RMB>>>  I think there are 2 parts regarding modules: 1) using CXF
from modularized
RMB>    RMB>>>  applications and 2) release/redesign CXF in a modular
fashion (I mean Java 9 modules).
RMB>    RMB>>>  The 2nd part is where we are heading eventually but we
won't be trully modular till
RMB>    RMB>>>  all our dependencies are available as modules as well. The
idea of adding
RMB>    RMB>>>  automatic module name is helping out with the 1st part.
Regarding your questions
RMB>    RMB>>>  though:

RMB>    RMB>>>  1. Adding module-info.java would mean, at least, to branch
the artifacts (java9+ / java8).
RMB>    RMB>>>  2. Yes, I think it makes sense, this is the recommended
way, but we should better make a
RMB>    RMB>>>  proposal first (as part of the JIRA Dennis created).
RMB>    RMB>>>  3. I think this is the only way (as module-info.java won't
compile with Java 8)

RMB>    RMB>>>  Automatic modules is a good start (arguably, for sure),
because from the efforts
RMB>    RMB>>>  perspetive, it looks doable in a short time vs adding
proper module-info.java to
RMB>    RMB>>>  each module, which would take significantly more. Thoughts?

with automatic
 RMB>>    RMB>>> module name?
 RMB>>    RMB>>> 2. For the naming it should really be someting like

 RMB>>    RMB>>> 3. Is it possible to double relezse each module, one with
the module info
 RMB>>    RMB>>> (if you do 1, or without the automatic module name if you
dont) and a
 RMB>>    RMB>>> qualifier jdk9 and keep current ones as today until the
