When using "Compare with previous" link in the "Edit Workitem" dialog an error is thrown stating: java.lang.IndexOutOfBoundsException: No group 6

This is appears to be related to there being a $ dollar sign in the content of the versions being compared. Removing the dollar sign allows comparison page to render.

The stack trace is (for version 1.0.3, similar but different exception in newer version):

java.lang.IndexOutOfBoundsException: No group 6

I have tried this with both Java 1.5 and 1.6 with the same results.

Steps to reproduce:

Go to http://demo.magnolia-cms.com
Open demo-project/service page
Edit the "Internal Page Teaser" by adding a $ to the "Teaser Overwrite" text
Activate changes
Open and edit the same page again
Submit the activation for approval
Use the "Compare with previous" link on the "Edit Workitem" dialog
See the error
