Make clone() a shallow copy? I don't think we should support shallow copying at
all - it's normally not going to be what a user really wants. One can still do
a shallow copy by directly setting the members.
{quote}
No, abusers of the reference API can create a deep copy directly by setting the
members. The onus is on abusers to have these extra lines of code, not for
correct users of the API.
{quote}
Is there even any code in Lucene or Solr that creates a shallow copy?
{quote}
Yes, and its uglier because of the problems above.

> Setting this as blocker for 4.0, as this class is used in every API there.
> Currently this API is a little of a everything, sometimes its like a

> We need this to be a ref to a byte[], nothing else. This other stuff can go
