Obfuscation causes Class.getEnumConstants to return null.

[ianthedead]

(occurs on version 1.7.0)

while the type of the class remains an enum, the enum constants in the class become regular fields.

also, (public enum a) becomes (public class a extends Enum)

Update: The issue happens with the MethodRenamerTransformer, ConstantTransformer and possibly some others, But it does not happen with the FieldRenamerTransformer or ClassRenamerTransformer, which is all I care about obfuscating when it comes to enums
