/**
* Indicates that a bean directly specializes another bean.
* May be applied to a bean class or producer method.
*
* If a bean directly specializes a second bean, it
* inherits:
*
*
* - all qualifiers of the second bean, and
* - the name, if any, of the second bean.
*
*
* If the second bean has a name, the bean may not
* declare a name using
* {@link javax.inject.Named @Named}. Furthermore,
* the bean must have all the bean types of the second
* bean.
*
*
* - If a bean class of a managed bean is annotated
* @Specializes, then the bean class must
* directly extend the bean class of a second managed bean.
* Then the first managed bean directly specializes the
* second managed bean.
*
* - If a bean class of a session bean is annotated
* @Specializes, then the bean class must
* directly extend the bean class of a second session bean.
* Then the first session bean directly specializes the
* second session bean.
*
* - If a producer method is annotated
* @Specializes, then it must be non-static
* and directly override another producer method. Then the
* first producer method directly specializes the second
* producer method.
*
*
* If a bean is specialized by any enabled bean, the
* first bean is disabled.
