Update on JDK 8 builds and release candidate status

[Joe Darcy]

Hello,

You've observed a known change in behavior:

     JDK-7131459 [Fmt-De] DecimalFormat produces wrong format() results 
when close to a tie
     https://bugs.openjdk.java.net/browse/JDK-7131459

The new result is actually numerically correct since the text string 
"85.55" does not get converted to a double value actually equal to 85.55 
it is converted to a value slightly less than 85.55.

HTH,

-Joe
