newObject() bug?

[Choi jung-pil]

I can't understand that why "sizeof(int32)" must used in
[newObject.c:59]
I think that
    sz = CLASS_FSIZE(class) * sizeof(int32) + sizeof(Hjava_lang_Object)
must replaced with
    sz = CLASS_FSIZE(class)  + sizeof(Hjava_lang_Object);
....
Is my mistake? please answer me~
