James E. King, III commented on THRIFT-4177:
--------------------------------------------
I just linked a number of issues in the backlog, some already done and some
not, to this issue.
It looks like there has been a desire to have a deep copy mechanism for a long
time.
Folks who use Java more should comment on this PR.

> Java compiler produces deep copy constructor that makes shallow copies for
> referenced objects from collections when they are defined after the root
> object in the thrift file.
> For example, consider following thrift file:
> struct Foo {
> 1: optional list<Bar> bars,
> }
> struct Bar {
> 1: optional string value,
> }
> new Foo().deepCopy() will produce a copy of Foo with a copy of a list that
> reference the same Bar object.
