RegexReplaceProcessorFactory replacement string support for match groups

Hi Hoss,

In RegexReplaceProcessorFactory, this line means that you can't use match groups in the replacement string:

    replacement = Matcher.quoteReplacement(replacementParam.toString());

What's the reasoning behind this? Or am I missing something here, and groups can be used?

It's making it hard for me to write up a simple solution to a training exercise, where students need to clean up incorrectly formatted dates :)

Thanks,

-- Ken

I filed a Jira on this as well back in May:
