>      Project: Geronimo
>         Type: Bug
>   Components: web
>     Versions: 1.0-M4
>  Environment: All
>     Reporter: Tom McQueeney
>     Assignee: Alan Cabrera
>     Priority: Minor
>      Fix For: 1.0
>  Attachments: JAASJettyRealm-patch.txt, WebRoleRefPermission-patch.txt, WebRoleRefPermissionTest-patch.txt
>
> The servlet isUserInRole call eventually gets delegated to
> org.apache.geronimo.jetty.JAASJettyRealm.isUserInRole, which causes a NPE in 
> javax.security.jacc.WebRoleRefPermission.hashCode().
> JAASJettyRealm.isUserInRole creates a WebRoleRefPermission, passing it the 
> null role that it was passed, then delegates the role check to 
> java.security.AccessControlContext.checkPermission, passing it the WebRoleRefPermission.
> When the web role ref permission gets checked, eventually its hashcode method is called,
> which tries to compute the hash by getting the hashcode of the (null) role name,
> which throws the NPE.
