A DESCRIPTION OF THE REQUEST :
I request that interfaces javax.swing.tree.TreeNode, javax.swing.tree.MutableTreeNode and class javax.swing.tree.DefaultMutableTreeNode define generic type for child nodes.


JUSTIFICATION :
TreeNode and descendants are a sort of container for child nodes, so it seem logic to apply the generic changes that were applied to the collection to the TreeNode also.

Subclassing DefaultMutableTreeNode is a common way to implement custom models. Now we have no control over what childs can be added to it. And we have to do a lot of class casting when dealing with actual children.

I think this is a good candidate for the generics.

P.S. Of cource, DefaultMutableTreeNode should also define generic type for userObject :)
