Github user jaikiran commented on the issue:
    I don't have enough knowledge about the thread safety aspects of the `Project` class.
Stefan (@bodewig) would know more. However, having look at its code, I see similar locks and
thread safety constructs for other members, so I think this change is fine.
    As for the testcase, I think it's OK to add one. However, the snippet that you pasted
might need some work. Right now, it uses a single thread and then in that thread's execution
runs the APIs of the `Project` class in a loop. So it really doesn't exercise the multi-thread
access behaviour and the access will all be sequential. What you could do is, use a fixed
thread pool with a decent size (10 perhaps) and then use a loop (of 10) to submit the `p.CopyOfReferences`
in that loop and finally `get()` the result for each of those `Future`s.
