Java 6 & AMD64

JIT в Java 6 update 4 на amd64 ужасно глючная вещь все время где-то падает (например eclipse падает на компиляции класса). Поэтому если нужно юзать java 6 на amd64, а оно падает, то можно заюзать ключик -Djava.compiler=none - это отключает JIT. Если цели использовать именно Java 6 нет, то можно поставить Java 5 update 14 оно вроде бы работает стабильно.
