  Only occurs when trace is turned off in the IBMJCEHYBRID
  provider.
  

Local fix

• The IBMJCEHYBRID provider can be removed from the list of
  security providers configured in either the
  $JAVA_HOME/lib/security/java.security file or within the
  application code.
  

Problem summary

• The Cipher.doFinal operation may throw a NullPointerException in
  certain circumstances when trace is turned off in the the
  IBMJCEHYBRID provider.
  

Problem conclusion

• An object that is set to null when IBMJCEHYBRID trace is turned
  off is no longer referenced. This should prevent the occurrence
  of the observed java.lang.NullPointerException.
