Why does my reg exp for the jakarta ant build tool not work?

\[javac\] \([[:alpha:]]:[^:]+\):\([[:digit:]]+\)

The only differences I see from the FAQ one...

^[ \t]+\[javac\] \([A-Za-z]:[^:]+\):\([0-9]+\):

...is that I use character classes, I don't check for leading white space, and I don't bother matching the : at the end. But my expression still matches the Filename and LineNum in the Ant output. It just doesn't work as a jump to expression.

Thanks!

The second regex has an ending colon, the first one does not?

Right, the trailing colon match is one difference. Regardless, my expression still matches the line. Plus, when used as a find and replace with "\1 \2" as the replacement expression it substitutes in those subpatterns properly. So why doesn't it work as a jump to?
