Recommended open source java mailing list software

Can anyone recommend a based open source mailing list software ?

The following would all be desired if possible:

Java as the underlying language, as we have people who are experienced with Java
Something which is packaged as a war and can be dropped into a Tomcat server
A sleek interface
Underlying data should be reasonably transparent
Good support for groups - sometimes we want to send mail to everyone, sometimes only people working in a certain area etc.

This is for a non-profit tax-payer funded research organization, so open-source (free) is a high priority. Thanks.
