BeanMetadata.getScope() returns "null"

[Martin Lichtin]

Hi
When BeanMetadata.getScope() returns "null", what is the scope of the bean?
I'd have expected the method to always return the scope.
The API is:

    /**
     * Return the scope for the bean.
     * 
     * @return The scope for the bean.
     * @see #SCOPE_SINGLETON
     * @see #SCOPE_PROTOTYPE
     */
    String getScope();
