RE: [dsdp-mtj-dev] MTJ backwards compatibility

["Raniere Hugo-wha006" <wha006@xxxxxxxxxxxx>]

Complementing Eric's e-mails,

If a bug is found that is worth correcting for Ganymede/Europa users, we
still can have maintenance releases for these platforms (this means
branching from 0.9.1, and if necessary merging the fix in the main
line).

 Craig,

The reason we chose to go with a 0.91 release was to ensure that we had
at least one more release that would maintain compatibility with
Ganymede. Once we get on the release train, our fear was that it would
be difficult to maintain backwards compatibility as we will primarily be
testing and developing with the milestones from Galileo. It is very easy
to introduce a Galileo dependency, and we don't really have a large
enough community to be able to do full regression testing against
Ganymede.

Fundamentally, the question comes down to are there any features that we
will be introducing in the first half of 2009 as part of the release
train work and can be built without Galileo features that we would need
to make them available to Ganymede users instead of using them on a
milestone build of Galileo? Are these features so valuable that we
should reduce our feature list for the release train in order to support
the additional regression testing required?

If there is a feature that gives a yes answer to both questions, then we
should include backwards compatibility as part of the plan. If not, then
I think we are better off focusing effort on the release train work.

(Trying to get caught up on MTJ stuff...)

Reading the meeting minutes from the last call, I see the following:

"After joining the train, Galileo specific features will be used  
(notable new JDT preprocessor) and therefore MTJ will only work with  
Galileo. "

It seems like it would be a good idea to continue to support older  
versions of Eclipse if/when possible.  With that said, I can see cases  
to allow certain functions to work on older versions while other  
features (preprocessing in this case) only work on newer versions.  I  
believe that is the approach of some of the plugins such as the  
Annotation processing stuff.
