Often the web console applet does not load with the following exceptions/message:
java.net.ProtocolException: Server redirected too many times (20)
...
load: class org.jboss.console.navtree.AppletBrowser not found.
java.lang.ClassNotFoundException: org.jboss.console.navtree.AppletBrowser
...
Caused by: java.io.IOException: open HTTP connection failed.
...
Flushing the applet cache (java console, pressing 'x'') and reloading the page than shows the applet. Is this a (known) bug?
