This NPE may happen if there is no running 
org.apache.geronimo.jetty.JAASJettyRealm GBean defining a Jetty specific 
realm having the name that you have declared in your web.xml file.

So, I think that you will need to define such a GBean having its name 
attribute set to the <realm-name> element of your web.xml file and its 
loginModuleName set to EXAMPLE.

Thanks,
Gianny
