Unsafe making too strong assumptions about array alignment?

My understanding is that Lilliput will change header size, not the way 
objects are aligned in the heap?

Header size affects the "offset" part, not the base part -- so my 
considerations remain? I think we're confusing header size with 
alignment of object in the heap -- the current Java impl of 
putLongUnaligned makes assumptions on the latter, not on the former.

Or is this more of a theoretical concern (e.g. an implementation "might" 
align objects at 4-byte boundaries) ?
