/**
* The presence of this annotation on a
* class automatically registers the class with the runtime as a managed
* bean class. Classes must be scanned for the presence of this
* annotation at application startup, before any requests have been
* serviced.
*
*
*
* The value of the {@link #name} attribute is taken to be the
* managed-bean-name. If the value of the name
* attribute is unspecified or is the empty String, the
* managed-bean-name is derived from taking the unqualified
* class name portion of the fully qualified class name and converting
* the first character to lower case. For example, if the
* ManagedBean annotation is on a class with the fully
* qualified class name com.foo.Bean, and there is no
* name attribute on the annotation, the
* managed-bean-name is taken to be bean. The
* fully qualified class name of the class to which this annotation is
* attached is taken to be the managed-bean-class.
* The scope of the managed bean is declared using one of {@link
* NoneScoped}, {@link RequestScoped}, {@link ViewScoped}, {@link
* SessionScoped}, {@link ApplicationScoped}, or {@link CustomScoped}
* annotations. If the scope annotations are omitted, the bean must be
* handled as if the {@link RequestScoped} annotation is present.
* If the value of the {@link #eager} attribute is
* true, and the managed-bean-scope value is
* "application", the runtime must instantiate this class when the
* application starts. This instantiation and storing of the instance
* must happen before any requests are serviced. If eager is
* unspecified or false, or the
* managed-bean-scope is something other than
* "application", the default "lazy" instantiation and scoped storage of
* the managed bean happens.
*
* When the runtime processes this annotation, if a managed bean
* exists whose name is equal to the derived managed-bean-name,
* a FacesException must be thrown and the
* application must not be placed in service.
*
* A class tagged with this annotation must have a public
* zero-argument constructor. If such a constructor is not defined on
* the class, a FacesException must be thrown and the
* application must not be placed in service.
