It's been several months since issue https://bugs.openjdk.java.net/browse/JDK-8039915 was reported in Java 8. This bug causes some very unexpected results from NumberFormat's HALF_UP rounding logic specifically, there are many cases where for two numbers x and y, x is > y, but round(x) < round(y). This issue is our only remaining blocker to migrate to Java 8.
Can anyone in Oracle provide an update?
