         * Need to be careful here. The test wants the exact content length
         * in bytes.
         * This will vary depending on where the test is run due to:
         * - The length of the version string that appears once in the error
         *   page
         * - The status header uses a UTF-8 EN dash. When running in an IDE
         *   the UTF-8 properties files will be used directly rather than
         *   after native2ascii conversion.
         *
         * Note: The status header appears twice in the error page.
