* The only reason this class does not explicitly implement the {@link IToolsLocator} interface
* is that it is used very early during the startup to check the validity of the installation.
* Actually implementing that interface causes other bundles to be activated before the
* Eclipse Platform is fully initialized, resulting in startup error.
