HttpNamingContextFactory is trying to install a default java.net.Authenticator to integrate the http credentials with the ejb calls, but this is a priviledged operation not allowed in an applet. This possible failure needs to be caught and ignored in org.jboss.invocation.http.interfaces.Util.init.
Does that mean that JBoss must be adapted or that my applet must be adapted?
JBoss or you need to sign the jar containing the org.jboss.invocation.http.interfaces.Util class.
Will this adaption be done automagically (by you?) or should I file a bug (?) report somewhere?
