I think we need to find out if the issue you are working around is a bug/issue with the virus checker or that Microsoft recommends that all applications should require to work these issues. As regards the patch then it is incomplete. If we are forced to put a workaround into the JDK code then I think it will have to do everywhere, not just for zip/JAR files.
