b5 crash on startup (b4 ok...)

[Thomas Arthur Oehser]

Hi, With b5, I'm getting:

08:40:44,392 ERROR main  [/xwiki]:listenerStart:3767 - Exception sending context initialized event to listener instance of class com.xpn.xwiki.web.InitializationServletContextLi
stener

...

SEVERE: Context [/xwiki] startup failed due to previous errors

Anything special I should look at?

B4 started up OK.

My environment is:

Linux 2.6.15-28-686
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)
Apache Tomcat/5.5.20

-Thanks, -Tom
