public class FixLaunchConfig extends Thread
Class to fix the launch configuration of a project if the java package defined in the manifest has been changed.
This fix can be done synchronously, or asynchronously.
start() will start a thread that will do the fix.
run() will do the fix in the current thread.

By default, the fix first display a dialog to the user asking if he/she wants to do the fix. This can be overriden by calling setDisplayPrompt(false).
