/**
* Load GeoServer configuration.
*
* <p>
* The existing getServer instances is updated with a call to load(..) based on
* the existing XML configuration files.
* </p>
*
* <p>
* It seems this class also creates the GeoServer instance in a lazy fashion!
* That would mean that if this class cannot load, the application cannot
* load? This could not possibly be the case, because the load action should
* only appear when logged in.
* </p>
*
* <p>
* Load need to remain on the current page, right now it takes us on a wild
* ride back to the welcome screen.
* </p>
*
* <p>
* Q: Does this need to load the Validation Processor as well?
* </p>
* @REVISIT: There seems to be quite a bit of code duplication in this class
* with GeoServerPlugIn, loading things, especially with the
* validation stuff. Anyway we could cut that down? Have one call
* the other? Too close to release to do sucha refactoring but
* in 1.4 we should. -CH
