jakarta regexp failing where jdk1.5 and gnu work fine...urgent prod issue

[Mike Klein <mi...@sbcglobal.net>]

I am working on an important production issue and am almost ready to
start pulling hair out.

I need to scrub emails from outgoing html and am using regexp for this.
I am stuck with regexp library for jdk 1.3 platform.

It works fine with JDK 1.5 impl and gnu-regexp...however gnu-regexp
fails when used in my appserver...so I'm trying jakarta impl. Problem is
that substitution seems broken and it's substituting OVER text that
needs to be preserved.

I will be working overnight to fix this issue and help is MUCH
appreciated...thanks.

You can see from below I am using same regexp (of course) across all 3
implementations.
