Ah, it seems that both are treated the same.  If you make such an array:

int[3][] a;
a.length = 5;

You'll find that the data for all the elements is contiguous, as with 
structs.  I wouldn't be surprised if the compiler would access the values in 
it using one pointer dereference instead of 2.

Fixed size arrays are weird, sometimes they're reference types and sometimes 
they're value types.  It's hard to remember when :S
