- L599 this is another case of "laundering" a conversion through a raw type (similar to Collections.java above), as we can't directly convert an Enumeration to Enumeration. As Remi noted in [4] this conversion wouldn't be necessary if Collections.enumeration() method were changed to take Collection<? extends T> instead of Collection. But that's an API change and should be handled separately. I'll file a bug on this.

There's already a bug on this, with some discussion:

http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6571613

The discussion revolves around how this interacts with type inference, and it mentions that "Smarter type inference may appear in JDK7." I know there have been type inference changes but I don't know how they would affect this case. Worth pursuing, anyway.
