JIDE Software created many new components that need their own ComponentUI classes and additional UIDefaults in UIDefaults table.
LookAndFeelFactory can take the UIDefaults from any existing look and feel
and add the extra UIDefaults JIDE components need.
Before using any JIDE components, please make you call one of the two LookAndFeelFactory.installJideExtension(...) methods.
Bascially, you set L&F using UIManager first just like before, then call installJideExtension.
