Same here.

It's really problem of setting status code to the meaningless (and invalid) "-1" \
value. Jetty fails on this line: return __responseLine[status];

Because it assumes that status code has valid (positive) and meaningful value. I \
strongly believe that default value should be 200 and will  commit change setting \
that because trunk is broken, now.
