I could see there is a mismatch in the generated jar (avro-ipc-1.9.2.jar) and
the sources of the jar.
>From the source: org.apache.avro.ipc.Responder.handshake
HandshakeRequest request = handshakeReader.read(null, in);
>From the jar:
HandshakeRequest request =
(HandshakeRequest)this.handshakeReader.read((Object)null, in);
