+/**
+ * {@link SdkToolsLocator} has two functions: <ul>
+ *  <li> It implements all the methods of {@link IToolsLocator} interface, and
+ *       so can be used as such. </li>
+ *  <li> It provides the {@link #isValidInstallation()} method to check the validity
+ *       of an installation. </li>
+ *  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.
