/**

 * Application class loader are under the control of the ArchiveHandler since
 * a special archive file format will require a specific class loader.

 * However GlassFish needs to be able to add capabilities to the application
 * like adding APIs accessibility, this is done through its parent class loader
 * which we create and maintain.

 * @param parent the parent class loader
 * @param context deployment context
 * @return class loader capable of loading public APIs identified by the deployers
 * @throws ResolveError if one of the deployer's public API module is not found.
