The Jython RE syntax is exactly the same as CPython2.0. What you have
encountered is a bug in the Microsoft JVM. 

To workaround the bug, you can either:

- Install some other JVM. I use javasoft SDK myself.
    http://www.javasoft.com/j2se/

- Enable the apache ORO matcher. You enable the ORO matcher by
  adding this line to your <jython.home>/registry file:
    python.modules.builtin = re

By rewriting the code a little bit, I have avoided the MS bug, so the
problem will not exist in the next release of jython.
