Got ServletException when submit http://www.vangoghgallery.com
This bug also appears if you try to validate the URL: http://www.prism.gatech.edu/~gth681y/
Same error reported for site http://rvbhute.org
We beleive that we found at least one direct cause of this using the "height: expression" technique to solve IE bugs min-height issue. Removing this solved the validation problem
Created attachment 522 [details] stylesheet with a question mark in rule
I reduced the bug to the presence of a question mark in CSS rules, which the CSS grammar does not allow for (only in quoted strings, URIs and other values but not in rules) but unfortunately IE encourages with its proprietary expression syntax. The question mark seems to confuse the tokenizer... (test case added here and in the validator's test suite)
Writeup on the issue in the CSS validator list: http://lists.w3.org/Archives/Public/www-validator-css/2008Feb/0033.html
fixed on qa-dev: The issue was in skipStatement, used very often to populate a CssError, but it was possible for it to fail with a TokenMgrError, now caught, and single char is read until the tokenizer can find something. (Note that this workaround might evolve in something else)
