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 is not the last attempt to set the name, the JAVA_MAIN_CLASS_ variable is used in the middle of the name selection, there are some others. And the "bin" is selected by some of the next step, I agree it is not a friendly name that could be improved.
