Error when trying to connect Corda Node using RPC

I am getting the following exception on the Node log, when i try to make a RPC connection from the client .The client.start() method seems to be stuck . The code is as follows. I am running this code from within a servlet hosted in Jetty .

        final NetworkHostAndPort nodeAddress = NetworkHostAndPort.parse("localhost:10008");
        final CordaRPCClient client = new CordaRPCClient(nodeAddress, CordaRPCClientConfiguration.DEFAULT);
        // Can be amended in the com.example.Main file.
        CordaRPCConnection clientConn= client.start("user1","password");

        rpcOps =clientConn.getProxy();

        rpcOps.waitUntilNetworkReady();

Below is the exception i see in the node log.

I ran into a similar issue in my testing and it turned out that my client library was a different version from the server. The error log shows that server has 3.2. What's the version of RPC you have on the client?
