http://www.w3.org/Bugs/Public/show_bug.cgi?id=4335

           Summary: HTML-style comments and markup in CSS confuses
                    validator, throws ServletException: Timed out
           Product: CSSValidator
           Version: CSS Validator
          Platform: Macintosh
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Parser
        AssignedTo: jean-gui@w3.org
        ReportedBy: ot@w3.org
         QAContact: www-validator-cvs@w3.org


Whenever the CSS parser of the validator finds HTML-style comments <!-- ... or
other similar syntax (doctype declaration too), the parser trips up and throws
the (wrong) exception ServletException: Timed out.

Debug info in console says: 

«
Exception in thread "servlet-runner:1"

Jean-Gui is looking into it: it seems to have been created by a fix [1] for bug
[2] 2919. Fixing appears to be tricky.
