-     * Lazily loads the available providers of this loader's service.

-     * loads and instantiates any remaining providers, adding each one to the
-     * cache in turn.
-     *
-     * <p> To achieve laziness the actual work of parsing the available
-     * provider-configuration files and instantiating providers must be done by
-     * the iterator itself.  Its {@link java.util.Iterator#hasNext hasNext} and
-     * {@link java.util.Iterator#next next} methods can therefore throw a
-     * {@link ServiceConfigurationError} if a provider-configuration file
-     * violates the specified format, or if it names a provider class that
-     * cannot be found and instantiated, or if the result of instantiating the
-     * class is not assignable to the service type, or if any other kind of
-     * exception or error is thrown as the next provider is located and
-     * instantiated.  To write robust code it is only necessary to catch {@link
-     * ServiceConfigurationError} when using a service iterator.
-     *
-     * <p> If such an error is thrown then subsequent invocations of the
-     * iterator will make a best effort to locate and instantiate the next
-     * available provider, but in general such recovery cannot be guaranteed.
-     *
-     * <blockquote style="font-size: smaller; line-height: 1.2"><span
-     * style="padding-right: 1em; font-weight: bold">Design Note</span>
-     * Throwing an error in these cases may seem extreme.  The rationale for
-     * this behavior is that a malformed provider-configuration file, like a
-     * malformed class file, indicates a serious problem with the way the Java
-     * virtual machine is configured or is being used.  As such it is
-     * preferable to throw an error rather than try to recover or, even worse,
-     * fail silently.</blockquote>
-     *
-     * <p> The iterator returned by this method does not support removal.
