Hi all,
I've a big problem matching really long Strings with jakarta-oro
2.0.1.
I'd searched the FAQ distributed by jakarta.apache.org and found
nothing matching my problem.
This is really my last chance, because i'd upgraded from oro-1.1 to
oro-2.0.1, but the bug is the same.
No the problem in detail:
I use this expression
/(.*)##(([^#\\|]|#[^#\\|])+)(\\|((\\w+://)?([^#]|#[^#])+))?##(.*)/"
...to match a text like:
"Im a text an i want to be ##linked##" URL="http://blabla"
The result of the match is parsed by groups in another routine. At
the text between ##, a URL should be inserted. On short texts, to a
length of 290 to 293 the Matcher works fine, but on a String, longer
than 290 chars the Matcher bounces between line 1043 and 1013 in

I'd tested the code under JRun 2.3.3 and Tomcat 3.2.1. The error
occurs on both engines. I hope you could help me to solve the
problem. Probably the expression is "to hard" for ORO?
I'd probed it with gnu-regexp and it's working fine with long strings,
but i'd to take ORO.
In hope for a quick answer,
