Ofc .. we have tested them and I just tried it here to be sure.

Please follow [1] first and save the java trace file,
then follow [2] and also save the java trace file.

[1] follow the FAQ bugreport page regarding applets
    to produce meaningful log files

[2] clear your java/jnlp cache manually
   - java control panel == control panel . java
     -> temporary internet files
         -> view
            -> select all and delete

In case [2] helps in your case, we may have an cache issue here.

Known issues:

Starting an applet w/ v2.0-rc9 _and_ w/ v2.0-rc10
in the same browser (and so often in the same JVM instance)
will not work and result in an indefined behavior.
Workaround would be to add a property in the applet tag
specifying the jogamp version.
