Нашли или выдавили из себя код, который нельзя назвать нормальным, на который без улыбки не взглянешь? Не торопитесь его удалять или рефакторить, — запостите его на говнокод.ру, посмеёмся вместе!

Жабовское байтоебство (судя по всему это такой ntohl) из реализации VNC.
Вот интересно, в жабке-то unsigned типов нет нихера, но почему-то сделали unsigned двоичный сдвиг (>>>), который работает для этих встроенных signed типов как если б это были unsigned. А как насчет unsigned умножения и деления (сложение и вычитание - то один хер, без разницы, если у нас two's complement)?
