PH44227: IllegalStateException occurs during portlet event processing within Portlet Container's CacheHelper Class

APAR status

• Closed as program error.

Error description

• IBMJCEPlus became the default JCE security
  provider in the service refresh 7 of the IBM SDK version 8.
  This caused Portlet Container to break since the MessageDigest
  implementations from IBMJCEPlus are not cloneable.
  

Local fix

• N/A

  ****************************************************************
  With service refresh 7 for IBM SDK version 8, the IBMJCEPlus
  became the default JCE security provider on some operating
  systems. However, the MessageDigest algorithms within
  IBMJCEPlus are not clonable (but are for IBMJCE).  Per the
  MessageDigest API, implementations are not required to
  implement the Cloneable interface. Nevertheless, this SDK
  change caused an unexpected
  java.lang.CloneNotSupportedException within the Portlet
  Container, resulting in the java.lang.IllegalStateException
  described above.

Problem conclusion

• The Portlet Container code has been updated to specifically
  use the IBMJCE provider in order to avoid this error.
  
  The fix for this APAR is targeted for WebSphere version
  9.0.5.12, and 8.5.5.22.
