Jeff Nelson updated THRIFT-2104:
--------------------------------
Description:
There seems to be 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
