Reinhard Sandtner updated JOHNZON-59:
-------------------------------------
Attachment: JOHNZON-59.patch
added a new test because it was easier to reproduce.
i will write more tests with other generic usecases and improve the fix but as
we have this issue in production we need a quick fix as first step
> broken mapping of generic types in inheritence hierarchy

> Key: JOHNZON-59
> URL: https://issues.apache.org/jira/browse/JOHNZON-59
> Project: Johnzon
> Issue Type: Bug
> Components: Mapper
> Affects Versions: 0.9.2-incubating
> Reporter: Reinhard Sandtner
> Priority: Critical
> Attachments: JOHNZON-59.patch
>
>
> 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.
