Good day. First, thanks for the cssparser project. It is a big help.
At the moment I am encountering two parsing bugs which are stopping me
in my current project.

One day I'll get my head around the javacc parser format; right now I
cannot. I did however created a testcase to show the problem I am
seeing. Is there any worksround for this bug ? Is there any way I can
patch the javacc files to handle these situations ?
