Re: [wtp-pmc] Request to use Java 5 Language Features in facet plugins


I hate to point it out, but facets *are* one of the more likely candidates for moving down to platform or other environments. Konstantin has been planning and working on this for some time, and there is already a proposed refactoring in CVS:

We can discuss further on the PMC call today.

Arthur, and others that may have forgotten ... the Eclipse Platform itself
has different requirements for each plugin, none of them 1.5.
The reason for that is they have real requirements to run in "small
footprint" environments, hence need to really hold back any extra

Eclipse as a whole, that is Europa, via the Planning and Architecture
councils, have stated that each project is free to choose their own, but
that they should "spec" the EE in the

Long ago, we (WTP PMC) agreed our committers were free to use Java 5
language features, "if they had a good reason" (e.g. to improve code
quality, but not just because they
personally liked the new for loop syntax :) and, naturally, subject to all
the other constraints we place on them (no breaking API changes, and even
extra care not to break non-api if there
were known users of it).

The one exception to our policy (due to my lobbying) was any plugin in the
"commons" component. There, I wanted explicit PMC review, since in some
cases there might be chances
these common plugins could "move down" to a lower level component in
Eclipse or there might be some adopter planning to use it in a reduced
footprint environment.
(One example of a 'move' is our attempts to move down some of our proxy
setting code).

Hence, Konstantin's request to the PMC, hence my affirmative reply and
request for others on the PMC to approve it for these facets plugins.

Thanks for asking.

Re: [wtp-pmc] Request to use Java 5 Language Features in facet plugins

Java 5 is getting fairly commonplace now so I don't see a problem in using
it to develop WTP, especially if it makes the code easier to maintain. Of
course, we need to be consistent with Eclipse policy. What are the Eclipse
Platform guidelines?
