Description
To improve source compatibility, after the initial generification of swing (), the return type of TreeNode.children was refined to allow covariant overrides (JDK-8054360). However, DefaultMutableTreeNode.children still returns Enumeration<TreeNode> rather than Enumeration<? extends TreeNode>. The latter would allow subclasses to return more precise information.
