Gregory Joseph updated MAGNOLIA-2659:
-------------------------------------

    Fix Version/s: 4.1

Added a testcase, and a commented out one that shows this fails with more than 
9 groups.
I have a fix locally, but more tests would help ensuring corner cases won't 
fail.

> I found that using a regexp with a high number of groups (>10) in a 
> RegexpVirtualURIMapping can cause a problem when replacing group instances 
> with matches.
> if you change 
> int matcherCount = matcher.groupCount();
> for (int j = 0; j <= matcherCount; j++) {
> in
> int matcherCount = matcher.groupCount();
> for (int j = matcherCount; j >= 0; j--){
> it works.
> This problem happens because the procedure replaces (in example) all "$2" 
> occurrences making impossible to find (and replace) the "$20"
