How to create ServiceClientFactory object when calling API from the same JVM as AEM Forms or LiveCycle

IN VM Passthrough strategy, create ServiceClientFactory object when calling API from the same JVM as AEM Forms or LiveCycle server.

Environment

AEM Forms/LiveCycle

Steps

We usually write following code when invoking LiveCycle/AEM Forms JEE java API through a remote client for getting ServiceClientFactory object: 

Properties connectionProps = new Properties(); 
connectionProps.setProperty("DSC_DEFAULT_EJB_ENDPOINT", "remote://localhost:4447"); 
connectionProps.setProperty("DSC_TRANSPORT_PROTOCOL", ServiceClientFactoryProperties.DSC_EJB_PROTOCOL); 
connectionProps.setProperty("DSC_SERVER_TYPE", ServiceClientFactoryProperties.DSC_JBOSS_SERVER_TYPE); 
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_USERNAME, "administrator"); 
connectionProps.setProperty(ServiceClientFactoryProperties.DSC_CREDENTIAL_PASSWORD, "password");

//Create a ServiceClientFactory object 
ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);

But in case, we want to invoke these APIs in a DSC or 'Execute Script' in workflow, we could easily use in vm direct pass through invocation strategy (which is default).
Use below code to get ServiceClientFactory object using IN VM direct passthrough strategy:

ServiceClientFactory factory = ServiceClientFactory.createInstance();

Additional information

See javadoc for details. EJB invocation (endpoint) could be used either remotely or from same jvm. In AEM Forms 6.x with Jboss 6.x, using EJB endpoint, we get following exception:

Though it is harmless, we could avoid this easily by using IN VM strategy, in case, we invoke it from same jvm.
