Why do you use such exorbitant, unreadable indentation for Usenet posts? You've been around a while and really ought to know better. Do you _want_ to discourage people from answering?

The indicated regex does not match that string. It only matches a substring of that string.
Check out the Javadocs for 'Matcher' for alternatives.
