Description

Similar to THRIFT-5527, this is the issue on the client side.

But unlike THRIFT-5527, this cannot be resolved by a fix on the compiler code. We managed to write a reflect based helper function to extract the IDL exceptions out of the result TStruct, I think upstream that helper function to be a provided ClientMiddleware would be helpful.
