> Please review this 2nd version of the fix taking into account your feedback.

I'm not recognized here as a reviewer, but the code looked OK to me and
it passed my patch test suite.

> I have merged HALF_UP and HALF_DOWN cases into a single switch case.

Good to know.  My current patch injects a method call to shim code
immediately after the HALF_UP case label.  I need to account for this or
else the applied patch could potentially cause HALF_DOWN to behave the
same as HALF_UP!  Thankfully, this is easily detectable in the bytecode
(not that the impact to my patch is of much concern to the core devs,
but it dove-tails nicely).

I'm looking forward to seeing this merged and the bug fixed/closed.  For my
company, the sooner this makes it into an 8u update, the better.  Thanks, Olivier.
