A DESCRIPTION OF THE PROBLEM :
When HttpServletRequest.setCharacterEncoding("KSC5601") is called from a servlet, java.security.AccessControlException is thrown.

HttpServletRequest.setCharacterEncoding() is implemented as follows:

        // Ensure that the specified encoding is valid
        byte buffer[] = new byte[1];
        buffer[0] = (byte) 'a';
        String dummy = new String(buffer, enc);

where 'enc' is the char encoding argument passed to HttpServletRequest.setCharacterEncoding().

String constructor throws java.security.AccessControlException, as shown in the following exception stack trace taken from the server log:
