Hmm

http://docs.oracle.com/javase/1.5.0/docs/guide/language/autoboxing.html

<cite>
So when should you use autoboxing and unboxing? Use them only when there 
is an “impedance mismatch” between reference types and primitives, for 
example, when you have to put numerical values into a collection. It is 
not appropriate to use autoboxing and unboxing for scientific computing, 
or other performance-sensitive numerical code. An Integer is not a 
substitute for an int; autoboxing and unboxing blur the distinction 
between primitive types and reference types, but they do not eliminate it.
</cite>

So, I'll agree that my assertion of logical equivalence is bollocks
However I'm still not convinced that mixing primitives and reference 
types is a 'good idea' in OO code.

But given the above I'll concede that suggesting Byte[][] was possibly 
poor advice, byte[][] might be better.
