Subject Re: [classlib][luni] String.toLowerCase/toUpperCase incorrect for supplementary characters (HARMONY-6649)
Date Fri, 24 Sep 2010 06:47:03 GMT
Hi Mohanraj,

Can you confirm which revision of the code you were running?  In
particular is it >= r1000700 which was the most recent application of
the patch for this issue?

(I'll be traveling over the next couple of days, so if there is still a
problem with this patch I'll ask somebody to revert it on my behalf and
I'll take a closer look when I'm home.)

Regards,
Tim
