>    Affects Versions: 0.9

> There seems to be an issue where structs lose their binary data when passed from server to client in Java. This can be illustrated using the repro steps below.
> 1. Create a simple struct that contains a binary field
> {code}
> struct TObject {
>         1: required binary data
> }
> {code}
> 2. Create a simple service that has a method that returns a TObject
> {code}
> service TService {
>         TObject get();
> }
> {code}
> 3. Generate java code for the struct and service
> 4. Create a server that implements TService.Iface
> {code}
> @Override
> 	public TObject get() throws TException {
> 		return new TObject(ByteBuffer.allocate(8).putLong(0));
> 	}
> {code} 
> 5. Create a client that calls to get get() function on the server and prints out the capacity of the return TObject's bytebuffer
> {code}
> TTransport transport = new TSocket("localhost", 1111);
> transport.open();
> TProtocol protocol = new TBinaryProtocol(transport);
> TService.Client client = new TService.Client(protocol);
> TObject obj = client.get();
> System.out.println(obj.bufferForData().capacity());
> {code}
> Expected: the capacity to be 8
> Actual: the capacity is 0, which indicates that the data was somehow lost during transmission
