Local fix

  • Using passbyref option with single classloader policy will
    workaround the issue - Collocated scenario
    

Problem summary

  • The problem is caused when processing meta for a class
    containing a field of type Serilizable.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR1
    6.0.1 SR2
    .
    The meta processing logic for classes with Serializable field is
    modified to resolve the issue.
