Hello,
i'm playing with webjars (https://github.com/eddyson-de/tapestry-webjars) and
jquery-ui. Everything work fine, except when i try to use the jquery-ui.css.
It took me some time to understand the following error message, while trying to
load the css file:
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).

The file %22images%2Fui-icons_555555_256x240.png%22 does really not exists.
Playing with SymbolConstants.STRICT_CSS_URL_REWRITING does not really help,
because the CSSURLRewriter fails too early.
The root cause is the *comment* header of jquery-ui.css. Within this header
exists the string "url(%22images%2Fui-icons_555555_256x240.png%22)".
I assume, it would be a good idea to either ignore comments or to be more
tolerant or catch the exception and then evaluate STRICT_CSS_URL_REWRITING.
What do you think?
Regards,
Robert
