For quick access, the sezpoz library stores lists in
META-INF/annotations/ of classes that have been annotated in a
special way.
To support the use case where the annotations actually changed since
sezpoz stored said lists, sezpoz then creates proxy instances for the
annotations to provide some backwards compatibility: as long as there
are default values for any newly-introduced annotation values,
everything is groovy.
Therefore, let's make sure that proxy instances inherit the
annotations' default values.
