Subject [jira] Commented: (COLLECTIONS-110) Support parametized classes with commons.collections.
Date Mon, 17 Nov 2008 17:19:44 GMT


Donal Murtagh commented on COLLECTIONS-110:

I think one person's dislike of generics is not a sufficiently good reason for rejecting this
request. Although many/most people feel that the Java implementation of generics is not ideal,
on balance, I believe that most people feel it's better than no generics at all. For example,
I don't know of any projects that are using Java 1.5+ but don't actually use generics.

Anyway, it seems like this issue is dead, but in case it is resurrected, I would emphatically
support a generic version of this library even if it is not 100% backward compatible, or uses
different package names so that it can co-exists with a non-generic version,
