Hi Jörg,

That was the confusing part: I don't actually use the "Optional" from
Guava myself, I have my own Optional class which isn't abstract. It's
just a container of a reference to the given type.

My question is then: shouldn't the parent converter use
getGenericType() instead of getType()?
getType() returns a class, so for a declared field Optional<String>,
it will only give me "Optional"; from getGenericType(), I would have
been able to get the "String" part as well.

Thanks for the suggestion. The multiple instances alternative sounds
doable for me.
cheers,
