[keycloak-dev] JSON document as claim JSON type on mapper configuration page

Hello Herbert,

the code that performs the value conversion is here:
org.keycloak.protocol.oidc.mappers.OIDCAttributeMapperHelper#convertToType

At the moment the only way to customize the mapping in the desired way is
to provide your own AbstractOIDCProtocolMapper mapper implementation.
Note that the OIDCAttributeMapperHelper is used by the setClaim method so
you need to avoid using that method, or replace the resulting
string value of your attribute with an object structure which is then later
marshalled as an appropriate json structure.

Cheers,
Thomas
