Comments
EVALUATION It is looks that the dummmyapplet (used for java.lang.System access) shares classloader with the first applet (JavaVer). Since 6u11, codebase lookup is set false for java package access. If that classloader is shared with an applet, the applet can not find flat classes from applet's codebase.
