3.0 SDK & generics

I've been working with the RTC 3.0 SDK and I've noticed that it's terribly inconsistent with regard to using Java generics.

For example, consider com.ibm.team.scm.client.IConfiguration: many of the methods in this class return collections but all with the exception of one return raw collections; com.ibm.team.scm.client.IConfiguration.fetchAncestorsByName(String, IProgressMonitor) is the exception.

Can anyone explain this inconsistency? It's not a show-stopping issue but my code is now littered with casts and @SuppressWarnings ("unchecked") and I find this very annoying.

I think the situation was that a lot of code got written before a generics-capable JDK started getting used. It would have been a very large effort to convert all existing interfaces, and would have broken API capability for existing consumers, so the older code was not updated.

See https://jazz.net/wiki/bin/view/Main/Java5AndJazzAPIs for a bit of discussion of this.
