Subject: Re: Unbelievable stack trace
FWIW, I found a regexp benchmark at
http://tusker.org/regex/regex_benchmark.html
The times I got on my laptop were
org.apache.regexp.* 14078
java.util.regex.Pattern 656
jregex.Pattern 1000
org.apache.org.text.regex.Perl5Matcher 1891
Wow, is o.a.regexp that slow? Should we move to java.util.regex
for 2.2?

I found this bug report for regexp with many duplicates. Apparently it is
pretty popular. I guess Vadim is aware of this. :-) The bug is closed
as WONTFIX.
