It's possible for us to set the name to something more friendly, for example, "Java", but I am not sure that should be launcher's responsibility to choose such a default name. It seems to me the consumer of the JAVA_MAIN_CLASS_%d environment variable should be responsible to pick such name in case the environment variable is not set.

Maybe the AWT folk should decide what name should be displayed in this 
case. The canonical name was chosen when all main classes had to have a 
canonical name. So perhaps a simple name will suffice in the case where 
there is no canonical name?

Cheers,
David
