Jeff Nelson updated THRIFT-2104:
--------------------------------
Description:
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
