>    Affects Versions: 0.9.2-incubating

> 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|https://issues.apache.org/jira/browse/JOHNZON-56] but since this got release I decided to create a new issue.
