Looks perfect to me.

Maybe you like to rename char variables to c, integers to i etc., just 
for sugar.

I'm not sure, if starting at offset 7/3/1 and then decrementing down to 
0 is the fastest way to step through the multi-byte values in makeType 
and get/putTypeL/B methods. They are anyway intrinsified little later. 
My guess is, we could save byte code and JIT optimization load by 
defining those methods as native calls, and user will not be confused, 
if those methods will perform slow on assembling the multi-byte values 
from single bytes.
