  ****************************************************************
  z/OS Connect was using an old version of IbmDoubleField.class
  which did not include the fix for Java APAR PM84401, which
  was affected by a defect which could cause the reported loop
  problem.
  

Problem conclusion

Temporary fix

Comments

• z/OS Connect has been changed so that the IbmDoubleField class
  provided by the Java installation is used. Ensuring that z/OS
  Connect runs with a current level of Java will prevent the
  affected IbmDoubleField class being loaded and used.
  
  The fix for this APAR is expected to be delivered by the PTFs
  for z/OS Connect V3.0.93.0 (PH66161).
