PHP_CodeSniffer 1.0.1 on a do while loop

While I fix lot of errors and warnings on my HTML_Progress2 package, there is one of them I don't understand On Preview.php file revision 1.7 [1], I got a : 80 | ERROR | Expected "do {\n...} while (...);\n"; found "...);\n" What's wrong on this code : Here is the loop (chunk of code extracted from [1])

        do {
            $percent = $bar->getPercentComplete();
            if ($percent == 1) {
                break;   // the progress bar has reached 100%
            }
            $bar->sleep();
            $bar->moveNext();
        } while(1);

I'll be please if someone can tell me an answer. Did I something wrong, or just a new PHPCS bug ? Laurent [1] http://cvs.php.net/viewvc.cgi/pear/HTML_Progress2/Progress2/Generator/Preview.php
