/**
 * Trivial implementation of TabbedContainerBridge for use with unit tests, etc.
 * Does not actually support changing tabs, this is just so things link and do not
 * throw NPEs.
 * 

 * Given sufficient interest, a JTabbedPane implementation could be provided,
 * though there are some non-trivial difficulties getting a JTabbedPane to show
 * the same component for all tabs, and the technique that worked on 1.4 does not
 * work on 1.5.
