/layout-admin-web/src/main/resources/META-INF/resources/init.jsp instantiates a LayoutsAdminDisplayContext object. This object adds an attribute in the request containing all layout descriptions.

All JSP including this init.jsp are executing this logic even when the attribute isn't used. This is specially relevant in 7.0.x where layouts_tree.jsp uses it and its loading that info every time the site administration menu is loaded.
