Subject [jira] Commented: (COLLECTIONS-110) Support parametized classes with commons.collections.

François LEIBER commented on COLLECTIONS-110:

I'm sorry to say this, but this discussion sounds like some old JDK bugs unsolved for years:
it sounds like a joke.
Yes, we know most people do their possible, that generics haven't been done perfectly and
sometimes give headaches, but Java5 is now 5 years old, and will finish its EOL in one month!
Who dares to say that generics are not used now in the majority of Java code over the world,
even in the industry? The truth is, this project (like other Apache commons), which should
greatly improve the base language, are instead largely useless. And I feel it's not because
nobody in the world can do the job, but rather because of some internal inertia. That's really
