Heye Vöcking resolved AVRO-1632.
--------------------------------
Resolution: Not a Problem
Fix Version/s: 1.7.7
I just realized that I did a mistake, so it is not a bug. What I did wrong is
that I called flush on the MemoryOutputStream {{out}}, but it has to be called
on the JsonEncoder {{e}}.
> C++ JsonEncoder dosen't close braces of objects
