As of Git 1.8.5 the symref information is reported as a capability:

https://github.com/git/git/commit/7171d8c15f919c760d52f814a0aee1b1253385b1

If you want to get this information, you are required to do all sorts of evil reflection, e.g.:

                Class<?> basePackConnection = BasePackFetchConnection.class.getSuperclass();
                Field remoteCapablities = basePackConnection.getDeclaredField("remoteCapablities");
                remoteCapablities.setAccessible(true);
                try (Transport transport = Transport.open(repo, url)) {
                    transport.setCredentialsProvider(getProvider());
                    try (FetchConnection fc = transport.openFetch()) {
                        fc.getRefs();
                        if (fc instanceof BasePackFetchConnection) {
                            Object o = remoteCapablities.get(fc);
                            if (o instanceof Set) {
                                boolean hackWorked = false;
                                for (String capability: (Set<String>)o) {
                                    if (capability.startsWith("symref=")) {
                                        hackWorked = true;
                                        int index = capability.indexOf(":", 7);
                                        if (index != -1) {
                                            references.put(capability.substring(7, index), capability.substring(index+1));
                                        }
                                    }
                                }
                                if (hackWorked) {
                                    return references;
                                }
                            }
                        }
                    }
                } catch (URISyntaxException | NotSupportedException | TransportException e) {
                    // ignore this is a total hack
                }

Please add the ability to get the symbolic reference information from LsRemoteCommand
