Security Manager for decryption is not set

Hey,

I am using the Livecycle virtual appliance in a test version to evaluate its features. When I decrypt an encrypted document with the java API I get an error message that says that the security manager is not set.

Is the security Manager part of the appliance?

How can I solve that problem?

My Code:

        //Set connection properties required to invoke LiveCycle ES                               
        Properties connectionProps = new Properties();
        connectionProps.setProperty(ServiceClientFactoryProperties.DSC_DEFAULT_EJB_ENDPOINT, getConfig("lc.ejb-endpoint.url", "jnp://192.168.56.50:1099"));
        connectionProps.setProperty(ServiceClientFactoryProperties.DSC_TRANSPORT_PROTOCOL,Service ClientFactoryProperties.DSC_EJB_PROTOCOL);         
        connectionProps.setProperty(ServiceClientFactoryProperties.DSC_SERVER_TYPE, "JBoss");
        connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_USERNAME, getConfig("lc.ejb-endpoint.username", "jjacobs"));
        connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_PASSWORD, getConfig("lc.ejb-endpoint.password", "password"));
                   
        //Create a ServiceClientFactory object
        ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);
           
        //Create an EncryptionServiceClient object
        EncryptionServiceClient encryptClient = new EncryptionServiceClient(myFactory);
   
        //Unlock the password-encrypted PDF document
        Document unlockedDoc = encryptClient.unlockPDFUsingPassword(pdf, pdfPassword);
       
        return unlockedDoc;
