VCO REST API Exception

I have written a program attempting simple communication with a VCO appliance using the REST web services API.  Here is the code I am running:

package com.vmware.vco;

import java.net.URI;
import java.net.URISyntaxException;

import com.vmware.o11n.sdk.rest.client.DefaultVcoSessionFactory;
import com.vmware.o11n.sdk.rest.client.SsoAuthenticator;
import com.vmware.o11n.sdk.rest.client.VcoSession;
import com.vmware.o11n.sdk.rest.client.VcoSessionFactory;
import com.vmware.o11n.sdk.rest.client.authentication.Authentication;
import com.vmware.o11n.sdk.rest.client.authentication.UsernamePasswordAuthentication;
import com.vmware.o11n.sdk.rest.client.examples.AbstractParams;

import com.vmware.o11n.sdk.rest.client.services.ExecutionContextBuilder;
import com.vmware.o11n.sdk.rest.client.services.ExecutionService;
import com.vmware.o11n.sdk.rest.client.services.WorkflowService;
import com.vmware.o11n.sdk.rest.client.stubs.ExecutionContext;
import com.vmware.o11n.sdk.rest.client.stubs.Workflow;

public class ConnectionTest {
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        VcoSession session;
        System.out.println("starting test");
        try {
            session = DefaultVcoSessionFactory.newLdapSession(new URI(
                    "https://10.25.49.38:8281/api/"), "vcoadmin", "vcoadmin");
            // create the services
            WorkflowService workflowService = new WorkflowService(session);
            ExecutionService executionService = new ExecutionService(session);
            // find a workflow by ID
            Workflow workflow = workflowService.getWorkflow("1231235");
            // create an ExecutionContext from the user's input
            ExecutionContext context = new ExecutionContextBuilder()
                    .addParam("name", "Jerry").addParam("age", 18).build();
        } catch (URISyntaxException e) {

            e.printStackTrace();
        }
        System.out.println("Exiting test");

    }
}

When the statement
            Workflow workflow = workflowService.getWorkflow("1231235"); is executed I am getting the following exception:

Exception in thread "main" org.springframework.web.client.ResourceAccessException: I/O error: peer not authenticated; nested exception is javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

    at com.vmware.vco.ConnectionTest.main(ConnectionTest.java:32)

As far as I can tell the creation of the session object worked just fine.  The exception appears to have something to do with the certificate.  I have imported the certificate from the VCO appliance into my cacerts file but I still get the exception.  I cannot find any information in the Developing a Web Services Client for VMware vCenter Orchestrator document relating to this issue.  If anyone has seen this and knows the resolution please let me know.
