On Font2DTest, strings of some Japanese characters in bold style are overlapped. hard to read.

Tested with jdk1.4 b64 on Japanese Windows 95 and NT4, and Solaris sparc 7 and 8 (eucjp) It doesn't occurred with jdk1.3 and jdk1.3.1 b24.

Steps to reproduce:
1)invoke Font2DTest with jdk1.4 b64 on Japaense windows and solaris sparc
2)Set Unicode range from 4e00 to 4ef0
3)Select Bold style:
4)Select Font size from 19 - 23, and 30 - 36
5)Select Method drawString, drawChars, drawGlyphVector, or TextLayout.draw

Some Japanese are hard to read because of overlapped strings. Unclear characters varies according to size within the range above.
