No encryption crypto object found exception in Apache CXF

Question

I am trying to build a Java client that communicates with .NET WCF services that use WS-Trust.

My .net STS uses WS2007Http binding and UserNameToken-based authentication, hosted on http endpoint.

var binding = new WS2007HttpBinding();
        binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
        binding.Security.Mode = SecurityMode.Message;
        binding.Security.Message.NegotiateServiceCredential = false;

The setting NegotiateServiceCredential is set to false to suppress using SslContextToken that is unsupported by Apache CXF.

My Java client code is following:

public static void main(String[] args) throws Exception {
    SpringBusFactory bf = new SpringBusFactory();
    URL busFile = Main.class.getResource("/cxf.xml");
    Bus bus = bf.createBus(busFile.toString());

    STSClient sts = new STSClient(bus);
    sts.setWsdlLocation("http://localhost:19308/MainTenantManager/SecurityTokenService?singlewsdl");
    sts.setServiceName("{http://schemas.microsoft.com/ws/2008/06/identity/securitytokenservice}SecurityTokenService");
    sts.setEndpointName("{http://schemas.microsoft.com/ws/2008/06/identity/securitytokenservice}WS2007HttpBinding_IWSTrust13Sync");

    sts.setSpnego(true);
    sts.setSecureConv(true);
    sts.setSoap12();

    Properties p = new Properties();       
    p.setProperty("org.apache.ws.security.crypto.merlin.keystore.type", "jks");
    p.setProperty("org.apache.ws.security.crypto.merlin.keystore.password", "pass1234!");
    p.setProperty("org.apache.ws.security.crypto.merlin.keystore.alias", "localhost!");
    p.setProperty("org.apache.ws.security.crypto.merlin.file", "keystore.jks");

    org.apache.ws.security.components.crypto.Merlin m = new Merlin(p);

    sts.getRequestContext().put(SecurityConstants.ENCRYPT_CRYPTO, m);

    sts.getRequestContext().put(SecurityConstants.USERNAME, "admin");
    sts.getRequestContext().put(SecurityConstants.PASSWORD, "qwe");

    sts.requestSecurityToken("http://localhost:19308/MainTenantManager/Service");

}

The result is an exception:

1437 [main] WARN org.apache.cxf.phase.PhaseInterceptorChain - Interceptor for {http://docs.oasis-open.org/ws-sx/ws-trust/200512/wsdl}SecurityTokenService#{http://docs.oasis-open.org/ws-sx/ws-trust/200512/wsdl}RequestSecurityToken has thrown exception, unwinding now

Which seems to be totally wrong since, the crypto object is set in code. I have tried both configuring the encryption though jaxws:client configuration using .properties file and setting it up in code.

What version of CXF are you using? The style of creating a Properties Object, and instantiating a Merlin Object with it + then using it for ENCRYPT_CRYPTO works with both the latest CXF trunk + 2.7.x-fixes code. If you are using an older version of CXF, perhaps try with a more recent version?
