APAR status

• Closed as program error.

Error description

• Error Message: N/A

  PC:28(Compiled Code))
  .
  The problem happens when method AlgorithmId.algOID was invoked
  concurrently from different threads.
  

Local fix

• N/A
  

Problem summary

• The problem happens because a static HashMap in AlgorithmId is
  accessed (read&write) by multiple threads at the same time
  without synchronization.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR6
  6.0.1 SR7
  6.0.0 SR15
  5.0.0 SR16 FP4
  .
  A fix is made to IBMPKCS to synchronize the code block which
  access the static HashMap
