  ****************************************************************
  When tracing a CICS service provider API, which flowed a
  container with no data, the tracing code did not calculate the
  data to be traced correctly, which caused a
  java.lang.ArrayIndexOutOfBoundsException.
  

Problem conclusion

Temporary fix

Comments

• z/OS Connect has been corrected to prevent the reported
  ArrayIndexOutOfBoundsException when tracing APIs which use the
  CICS service provider.
  
  The fix for this APAR is expected to be delivered by the PTF for
  z/OS Connect V3.0.99.0 (PH68482).
