I'm experiencing a NPE in Jboss 5 when I try to check the request for a specific role. Example code below:

if (request.isUserInRole("Employee"))
System.out.println("not employee role");
else
System.out.println("employee role");
}

returns:
java.lang.NullPointerException
org.jboss.web.tomcat.security.JBossWebRealm.hasRole(JBossWebRealm.java:528)
org.apache.catalina.connector.Request.isUserInRole(Request.java:2184)

This is through the container performing the authentication. The same method works fine under Jboss 4.0.3SP1, but migrating to Jboss 5 gives this error.

I know my roles are available, as accessing role information through SecurityAssociation works fine.

Any help would be appreciated. I'm unsure if this is a configuration error, or an error in Jboss 5.
