Hi, I am not sure, but to me it looks like the problem on HTTP level (guess 404). Also I would try to capture the good case (with C++ client) and the bad case (Java) with Wireshark / snoop and compare the HTTP request. However it looks strange, but I would guess some different interpretation of "sample.add"
