Description

If the css header comment part contains a pattern like 'url(file_not_found)' the procedure AssetSource.getAsset throws an RuntimeException and prevents further processing, especially testing for null and evaluating StrictCSSURLRewriting.

Caused by: java.lang.RuntimeException: Unable to locate asset 'webjars:META-INF/resources/webjars/jquery-ui/1.12.1/%22images%2Fui-icons_555555_256x240.png%22'
(the file does not exist).
