PM78827: When an unsigned 64-bit integer is used within a class in a C# application an FFDC record is generated.

APAR status

• Closed as program error.

Error description

• When an update is performed using a Uint64 value ( which is
  only possible using the C# .NET support ), an FFDC exception
  occurs that contains the text "XFError: XDF Error: Fields
  still need serializers".
  The update performs successfully, but the logic that merges
  the previous version of the data with the new value as part of
  the XDF class evoluion support will not be performed.  This
  will mean that all fields that do not exist in the current
  value's version are lost.  If you only have one version of the
  value class that contains the Uint64, then this FFDC message
  can be ignored.

  ****************************************************************
  An eXtreme data format (XDF) serializer was added for C#
  unsigned
  64-bit integers (Uint64).
  

Problem conclusion

• XDF now correctly serializes and deserializes C# unsigned
  64-bit integer (Uint64) and FFDC messages not generated.
