The Menu character can't render clearly when I run testcase CheckboxMenuItemRenderTest4 on RedHat_amd64-5-zh_CN.UTF-8, Refer to Screenshot in attachment for detail.

platform: Redhat_amd64-5
locale: zh_CN.UTF-8
build: http://jre.sfbay/java/re/j2se/5.0u15/promoted/rev/b11/j4b/bundles/linux-amd64/jdkfb-1_5_0_15-rev-b11-linux-amd64.bin

Reproduce this bug:
1. set JAVA_HOME to 5u15 b11
2. run $JAVA_HOME/bin/java -jar CheckboxMenuItemRenderTest4.jar

MenuItemRenderTest4.java is test source code.
