IZ99401: OBJECT REFERENCES MISSING IN PHD HEAPDUMPS

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  PHD heapdumps contain incorrect references between objects. The
  typical symptom is a self reference back to an object, when
  there should
  be a reference to a different object. For example, a
  java.lang.String object may have a reference to itself, instead
  of to a character
  array. When using tools to examine the heapdump the problem may
  show up as excessive number of roots.
  

Local fix

• Use a system dump for diagnosis instead of a heap dump
  

Problem summary

• The problem is caused by incorrect code in the JVM heapdump
  writer.
  

Problem conclusion

• This defect will be fixed in:
  5.0.0 SR13
  .
  The JVM has been updated to correct the heapdump writer to
  provide correct references between objects.
  .
  To obtain the fix:
  Install build 20110428 or later
  

Temporary fix
