I found that the JOptionPane must not have a separator component
installed between the top and bottom JPanel. I have an application
(using a custom L&F) here that depends on the JOptionPane only having
two child components.

* javax/swing/plaf/basic/BasicOptionPaneUI.java
(createSeparator): Return null here.
(installComponents): Don't add a separator in the OptionPane.
