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.

Both issues involve a problem trying to use the canonical name, but I'd 
consider both fixes deficient when an alternative name could be used. 
But this isn't my code so ...
