Tianyi Wang commented on THRIFT-1833:
-------------------------------------

I believe this duplicates THRIFT-3650 and is fixed in 0.10.0.

> The generated union struct c++ writer would write all union fields. This is incorrect. It should only write the field that has been set.
> It causes incompatibility between c++ and Java. A union written by C++ side cannot be read by the Java side.
