  /**
   * Initializes DLTKCore internal structures to allow subsequent operations (such as the ones that
   * need a resolved classpath) to run full speed. A client may choose to call this method in a
   * background thread early after the workspace has started so that the initialization is
   * transparent to the user.
   *
   * <p>However calling this method is optional. Services will lazily perform initialization when
   * invoked. This is only a way to reduce initialization overhead on user actions, if it can be
   * performed before at some appropriate moment.
   *
   * <p>This initialization runs accross all Java projects in the workspace. Thus the workspace root
   * scheduling rule is used during this operation.
   *
   * <p>This method may return before the initialization is complete. The initialization will then
   * continue in a background thread.
   *
   * <p>This method can be called concurrently.
   *
   * @param monitor a progress monitor, or <code>null</code> if progress reporting and cancellation
   *     are not desired
   * @exception CoreException if the initialization fails, the status of the exception indicates the
   *     reason of the failure
   * @since 3.1
