Шаблон этого параметра
java -Djava.library.path={natives_path} -cp {classpath} net.minecraft.client.main.Main --accessToken null --version {version}
В принципе ничего сложно, просто classpath толстоват!
Произвел дамп аргументов JavaVM
Увидел что обычные аргументы идут в sun.java.command, а {classpath} указывается в java.class.path, {native_path} в java.library.path.
Ну ладно, раз так все просто, делаю следующее.

И не запускается! Что-то не так с этими аргументами -Dsun.java.command=net.minecraft.client.main.Main --accessToken null --version 1.8.7
Видимо их указывать нужно по другому, кто вкурсе? И можно ли логи jvm перенаправить в обычный вывод Qt?
