When doing a substitution, jakarta regexp and oro will both consider the $g syntax, but ignore it if the $ in your replacement string isn't a digit, and simply return the $ untouched.
Java Regex, on the other hand, throws an exception if the character after the $ isn't a digit. The only way to handle it for now is to escape the $ with \ in the replacement before doing the substitution. Tiger will have a fix that can just turn the thing off entirely, but fat lot of good that does me now...
Should have just used jakarta-regexp to start with...
Actually, I played with extracting the "commons" (but not officially "commons") regex wrapper layer that Ant has, and I probably should have continued using that instead; it would allow me to quickly switch to a jakarta regex library without any code-changes. I might release that extracted codebase someday...
