A DESCRIPTION OF THE PROBLEM :
RoundingMode.HALF_UP gives different results with NumberFormat

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided code. You will see the following output:

0.675 -> 0.68
12345.675 -> 12,345.67

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
0.675 -> 0.68
12345.675 -> 12,345.68

---------- BEGIN SOURCE ----------
NumberFormat numberFormat = NumberFormat.getNumberInstance(Locale.US);
numberFormat.setMaximumFractionDigits(2);
numberFormat.setMinimumFractionDigits(2);
numberFormat.setRoundingMode(RoundingMode.HALF_UP);

System.out.println("0.675 -> " + numberFormat.format(0.675));
System.out.println("12345.675 -> " + numberFormat.format(12345.675));
---------- END SOURCE ----------

FREQUENCY : always
