> Now that HARMONY-5889 has been incorporated, the .equals() method for ByteCode can be
simplified. This leads to some performance increase.
> I've also modified the hashCode() method. It now leads to fewer collisions. Now there
are as few as if Object.hashCode() were used instead. (I didn't use Object.hashCode() because
the abstract hashCode() in ClassFileEntry means I'd have to put a helper method in ClassFileEntry
- and if the code in ByteCode is just as fast, why do that?)
