>
> Currently we are trying to speculatively guess field ID and order. If
> speculation succeeds (which is almost always true during normal
> deserialization) we have pretty cool performance gain.
> However, when speculation succeeds we still reads field position from footer.
> There is no need for this actually. Instead, we can rely on the fact that
> stream is already positioned correctly.
> To employ this technique we must ensure that when field is read, stream
> pointer is always set right after the field. Currently this is not the case
> for "unmarshal" and "doReadPortableObject" methods in reader. They must be
> reworked to allow for this opto.
