Description

We heavily use json for saving arbitrary objects as json-string in database.

if you have a inheritance hierarchy of more than 1 with a generic declaration, deserializing the string fails with

• ClassCastException - Cannot cast sun.reflect.generics.reflectiveObjects.TypeVariableImpl to java.lang.Class if the JavaType f.e. java.util.Long was serialized as a JsonString
• MapperException: Unable to parse 478965 to T if the JavaType was serialized as JsonNumber

maybe this is a follow up error from JOHNZON-56 but since this got release I decided to create a new issue.
