the code section that is failing is
The method source:

   From AnnuityConstants class file
   final public static char [] VAR_ANNUITIZED_STATUS = {'O','P','0'};
   final public static char [] FIX_ANNUITIZED_STATUS = {'0'};

   /**
    *Return true if it is a Annutized Contract.
    */
   public boolean isAnnuitized() {

      char [] annuitized = null;
      char contractStatus = ' ';

      if(mAnnuityContract.isVariable()) {
         annuitized = AnnuityConstants.VAR_ANNUITIZED_STATUS;
      } else {
         annuitized = AnnuityConstants.FIX_ANNUITIZED_STATUS;
      }


      try {
         contractStatus = mAnnuityContract.getContractStatus();
      } catch(AnnuityException ae) {
         AnnuityLogger.error(this.getClass().getName(),"isAnnuitized(),
Error occurred while attempting "+
                             "to check Annuitized status or not" + ae,
Layer.LAYER_BUSINESS_LOGIC,
                             AnnuityErrors.GENERIC_EXCEPTION_CODE);
      }

      if(annuitized != null) {
         for(int i = 0; i < annuitized.length; ++i) {
            if(contractStatus == annuitized[i]) {
               return true;
            }
         }
         return false;
      } else
         return false;
   }

We can see that the optimizer might be interested in removing the if
because annuitized can never be null.
Also, since one of the two constant arrays is 1 byte in length, it could
remove the loop for one of the branches of isVariable()..
The core implied that an empty loop was being removed.
