Jawr fails with the css property content

Question

In my css I have a selector like this

a[href]:after {
   content: " (" attr(href) ")";
}

Jawr trips over the " (" and the ")". If I remove them, it works fine.

The exception I get when starting tomcat to deploy the web-app is:

SEVERE: Exception invoking method manageApp
java.lang.StackOverflowError
    at java.util.regex.Pattern$BmpCharProperty.match(Pattern.java:3714)
    at java.util.regex.Pattern$Ques.match(Pattern.java:4085)

    at java.util.regex.Pattern$CharProperty.match(Pattern.java:3694)
    at ... etc etc etc

Anybody any idea how to make Jawr eat my original selector without choking? I'm using the latest Jawr 3.3.3
