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.

This file is mostly based on the bug report as I just adjust static keyword to make sure we cover different cases, thus I am not sure whether to add copyright or not.
