IJ03607: RESULT STRING CONTAINS A REDUNDANT DOT WHEN CONVERTED FROM BIGDECIMAL WITH 0 ON ALL PLATFORMS

APAR status

• Closed as program error.

Error description

• Error Message: String foo(NumberFormat format, BigDecimal
  bigDecimalValue){
     String str = format.format(bigDecimalValue.doubleValue());
     return str;
     }
  The above method expects the result String to be "0" when
  bigDecimalValue is 0 but gets "0."
  .
  Stack Trace: N/A
  .
  This error happens more often at hot and scorching compilation
  level
  

Local fix

• -Xjit:disableStringPeepholes
  

Problem summary

• The issue results from a JIT compiler optimization which makes
  it faster to change a BigDecimal number to a String according to
  a given format. The optimization missed the case of value zero
  when deciding if a dot is needed in the result String.
  

Problem conclusion

• The optimization has been fixed to take 0 as a special case to
  avoid adding the redundant dot.
