Since the String table (for the <clinit> name) is shared the only real overhead is a single entry in the method reflection table (12 bytes on a 32 bit architecture) If the class object had a pointer this would be 4 bytes. So that would be only 8 bytes of saving, but the class initialization time would be faster as you would not have to do a lookup in the method table.

That is not correct. I think the actual size of the method reflection entries is 20 bytes each.
