finalize() method

I have one doubt.
I am using VERY BIG Help file in JEditorPane ( to show online help) as follow.
URL url = ClassLoader.getSystemResource(fileName);
pane = new JEditorPane(url);
Now what should I make null, in finalize method, to free up non java resource ?
should it be url ?
or pane ?
i.e. should it be url = null;
or pane = null; in finalize method.
thanks in advance.

If url is a class member, you should set both to null. If it's a local reference that goes away on the completion of its enclosing method, it would seem like setting pane to null is sufficient.
There's no significant cost in dong both when you're not sure, though.
