IV59946: HASHMAP.WRITEOBJECT() WRITES INCORRECT DATA TO THE STREAM

APAR status

• Closed as program error.

Error description

• Error Message: MarshalException when CORBA tries to deserialize
  a class that extends HashMap class with custom get/put/size
  calls. The problem may arise even if the class is deserialiazed
  through a custom deserialization class.
  .
  Stack Trace: N/A
  .
  

Local fix

• Use default java.in.ObjectInputStream class for deserializing,
  if possible.
  

Problem summary

• The problem arises due to duplication of the data held by the
  class extended by the HashMap while serializing its instance.
  Default ObjectInputStream deserializes the object without this
  extra data. But the problem may arise with any other
  ObjectInputStreams.
  

Problem conclusion

• The code is fixed to avoid the duplication of data while
  serializing the stream.
  .
  This APAR will be fixed in the following Java Releases:
     6    SR16 FP1  (6.0.16.1)
     6 R1 SR8 FP1   (6.1.8.1)
  .
