hg: amber/amber: adding runtime support for sealed types

[Remi Forax]

Hi Vicente,
for the code of isSealed, i believe that an empty sealed type is a valid degenerate case, it may be not valid in Java the language, but it's a better representation of a typed null than a class with no constructor that javac uses for generated accessor constructor.

cheers,
Rémi
