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.
  

Temporary fix
