      Description

      Steps to reproduce:

      • store data in cache stores by JDG 7.0.0 or older
      • read the data back with JDG 7.1.0
        The result is NullPointerException and the data cannot be read back.

      Partial stack trace:

      Full stack trace attached.

      A dummy workaround would be to use GlobalConfigurationBuilder().serialization().marshaller() and set the previous version of the marshaller. But that would affect all marshalling, AFAIK.
