I've switched from Hudson to Jenkins and replaced the WAR file on my server.

I've a maven project which executes and fails (to my surprise since the build says:

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 12:54.421s
[INFO] Finished at: Fri Feb 04 10:18:08 CET 2011 [INFO] Final Memory: 32M/106M [INFO] ------------------------------------------------------------------------

but that's another topic).

The generated email:

Subject: Jenkins-Build fehlgeschlagen (german for failed): <PROJECTNAME> #8

Body:
Siehe (german for 'see') <http://<mybuildhost>:8080/hudson/job/<PROJECTNAME>/8/>

<CONSOLE_LOG>

As you can see the webapp context is 'hudson' instead of 'jenkins'.
