> JaninoRelMetadataProvider uses the a complicated convention for binding
> handler instances to a the dynamically created handler. It requires the
> method to stated once in Metadata, then again MetadataHandler with slightly
> different signature and finally again a reference to the Metadata method must
> be included MetadataDef. This is needlessly rather complicated and verbose
> for something that is trying to reduce boiler plate.
> Having JaninoRelMetadataProvider get the declared methods directly from the
> handler interface would decouple JaninoRelMetadataProvider from method
> definitions in Metadata and MetadataDef.
