RE: [wtp-dev] FW: Arrays vs. Collections in new API

Arthur,
 
1) Do you mean we need to stage API changes during the 1.0 development cycle in such a way that dependent plugins have a chance to migrate with no functionality outage?  If that's what you mean, I totally agree that we shouldn't be checking in api changes that cripple layered WTP functionality for a period of time.
 
2) Or do you mean there are some 0.7 APIs that must be preserved in the 1.0 release because of binary compatibility commitments?

Kosta et al,

We need to think carefully about the evolution of APIs in general. In some cases, we may have to preserve the old ones and provide new parallel APIs that coexist with them. Plug-ins can then migrate to the new ones incrementally.

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?
