Hi Mark--

The /[^throw]/ regexp isn't doing what you think it's doing-- you've created a character class (with the square brackets) containing the letters 't', 'h', 'r', 'o', and 'w', and are matching on anything that doesn't contain those (the ^ negates a character class. So if the throw line in your Java contains ANY characters that aren't t,h,r,o, or w, it'll match. This is why you're getting unexpected behaivior.

You're on the right track with using !~. That should do what you mean.

Try running "perldoc perlre" on your local system for a good intro to this type of thing.
