Annotation-based introspector does not include super-class fields

[cowtowncoder]

Optional AnnotationBasedIntrospector extension (added in 2.11) replaces standard property introspection logic, but seems to accidentally omit inclusion of super-class fields (unlike basic implementation).

Fixed in 2.12 for 2.12.1; also backported in 2.11 in case there will be 2.11.5 (which is not certain).
