AOT-компиляция Minecraft

Скажу сразу: я далеко не спец в вопросах программирования на Java и в глубоких технических деталях. Делаю все это ради личного интереса, а потому просьба - тапочками сильно не закидывать.

Собственно, задачка:
Скомпилировать клиент Minecraft с навешанными на него Forge и Optifine с помощью Excelsior JET.

Решил я пару дней назад поэкспериментировать с моей сборочкой и слегка повысить ее производительность. Погуглив, я наткнулся на интересную тему на minecraftforum, где обсуждалось использование AOT-компиляции и обещалось повышение производительности в 2-3 (!) раза, подтвержденное реальными тестами. Узнав о таком, я тут же кинулся ставить Excelsior JET и компилить игру в нативный код. Оригинальный клиент версии 1.5.2 скомпилировался хорошо, скорость запуска немного увеличилась, мир стал создаваться несколько дольше, но чанки грузятся в 2-3 раза быстрее. Влияние на FPS было минимальным (относительно моих ожиданий), в среднем, частота кадров увеличилась на 15-20%, вместо обещанных 200%-300%. Проблемы появились при начале попыток скомпилить игру с Forge и Optifine.
При тестовом запуске игра сперва нормально загружается, Forge проверяет и грузит свои библиотеки, но потом клиент вылетает со следующей ошибкой:

Подскажите, из какого места растут мои руки что я делаю не так и возможно ли вообще скомпилировать клиент с Forge и Optifine.
Заранее спасибо.

 

Не получится нормально, слишком много манипуляций с байткодом.

Да и смысла мало, выигрыш в 2-3 раза только на очень и очень слабых машинах, в остальных случаях в 20 процентов максимум, а сразу после того как отрабатывает JIT вообще никакой.

 

Фордж слишком активно пользуется ASM

 

Т.е. проще говоря, источником проблем является Forge, сам по себе ворошащий
...исходный код?
