No, I
think we're primarily interested in "future proofing" the
api.
Yes,
we lose the strong typing offered by arrays in the short term, but we gain
binary compatibility when we are finally allowed to convert to
generics.
Except
for the most memory sensitive situations (and in fact I think
Konstantin actually found that he was using more memory implementing an array
based api), I believe that most people will be adopting generics in the
near future.
Once
you've tasted the generics koolaid, it's really painful to encounter
an array based api :-)

Thanks for "netting this out", Konstantin.
Its a good question, and a good time to ask, since normally, I think, Arrays are preferred over Collections (for performance reasons),
but as mentioned in the longer append, returning immutable collections is a good way to improve thread safety.
(I assume it the thread safety you're primarily interested in?)
I doubt we could find or agree on a "whole WTP approach" so if you know of any specific cases or areas, you might
point those out in feature requests with some assessment of impact, performance JUnits, etc.
Thanks for raising this.

No, we are not proposing to move to Java 5.0 for the 1.0 release. What the conversation was about and what we would like to propose to WTP as a whole is to consider moving to using unparameterized Collections in the API for the 1.0 release. Then, when platform and WTP moves to Java 5.0 (3.2/1.5?), the APIs can be changed to use parameterized collections without breaking binary compatibility.
Thoughts?

This was interesting ... but to be clear, our 1.0 will be on Eclipse 3.1.1 and, I'm guessing, when
Jim said "in the fall they will start to use Java 5.0" I suspect he meant for the 3.2 stream.
Are you suggesting we standardize on Java 5.0 for our API and 1.0 release?
If so ... seems like a huge step, to me.
So ... just thought I'd ask for clarification ... maybe you were just sharing
an interesting discussion?
