Currently, Configuration's update() method returns a boolean whether the update was successful or not. I feel there is some room for improvement here, for this method (or a relevant sibling method) to return more details about the update. Namely:

• message/reason for the update failing (if any)
• whether (or how many?) jars were actually updated, or there was nothing newer to get
• what is the current version of the business application jar (The one defined in Maven's <version /> In the business app I can get it by getClass().getPackage().getImplementationVersion())

That way updates could be logged and various feedback could be provided based on the update wizard (i.e. a popup displaying that a new version is now running, possibly linking to a change log).
