I'll still need that AnnotatedElementMetaDataLoader field change, for non-public fields.
It's the way I do annotation lookup in AbstractBeanAnnotationAdapter, going over MetaData to do the lookup:

  |             FieldInfo field = pi.getFieldInfo();
  |             if (field != null)
  |             {
  |                Signature sis = new FieldSignature(field);
  |                MetaData cmdr = retrieval.getComponentMetaData(sis);
  |                if (cmdr != null)
  |                {
  |                   for(AnnotationPlugin plugin : fieldAnnotationPlugins)
  |                   {
  |                      if (isApplyPhase)
  |                         plugin.applyAnnotation(field, cmdr, visitor);
  |                      else
  |                         plugin.cleanAnnotation(field, cmdr, visitor);
  |                   }
  |                }
  |                else if (trace)
  |                   log.trace("No annotations for field " + field.getName());
  |             }
  | 
If the field is non-public and the mode is non-standard, this field will be a part of propertys, but I don't want to distinct between underlying annotations and instance annotations (which are only in metadata, right).
