  I noticed there are some big changes where the Locale changes 
shouldn't affect, like this one.

Test  : java/util/AbstractMap/ToString.java
Old   : 0.0084 (Min=0.0070, Max=0.0110)
New   : 0.0270 (Min=0.0070, Max=0.1050)
Change: +221.43%

Is the performance measurement reliable?

Thanks,
Masayoshi
