    The object becomes eligible for collection immediately,
but there is no guarantee of exactly when the collection will
occur.  There is not even a guarantee that collection will occur
at all: if your program never runs short of memory, the JVM may
simply allow the garbage to hang around indefinitely.

    Please provide more detail on what you think "is generally
done in Swing."  As far as I know, the JFrame will not become
visible until you call its setVisible() method -- for which you
need to have a reference to the JFrame.  Once the JFrame has
been made visible, Swing keeps its own internal references to
it even if you discard your own.
