        Use the newly added improved UTF-8 decoder for decoding UTF-8 encoded
        URIs and UTF-8 encoded request bodies. Invalid UTF-8 URIs will not
        cause an error but will make use of the replacement character when an
        error is detected. This will allow web applications to handle the URI
        which will most likely result in a 404 response. The fall-back to
        decoding with ISO-8859-1 if UTF-8 decoding fails has been removed.
        Invalid UTF-8 sequences in a request body will trigger an IOException.
        The way the decoder is used has also been improved. The notable change

        allow failed web applications to be started once the configuration
        issues have been resolved. Any changes to a context.xml file (global,
        per host or web application specific) will now result in a redeploy
        of the affected web application(s) that ensures that any changes are
