Bug 896640

+++ This bug was initially created as a clone of Bug #896634 +++

Description of problem:

Customer has raised the point that JBpmObjectMapper doesn't make it to what appears to be the intended log statement when a jBPM-side variable is not present.

This can be validated by inserting the following method into JBpmObjectMapperUnitTest.java:

// Same as existing test, just commented out setting v1.

    @Test
	public void testMissingObject() throws Exception
	// Things to look for:
	// 1) If the variable does not exist in the jbpm variable map, the execution context is tested, but if not present there, an exception is thrown.
        // It looks like the intention was to arrive at "log.warn("The object " + mapping.getBpm() + " is null and cannot not be set on the message")"
	{
        SAXReader reader = new SAXReader();
        Document document = reader.read(this.getClass().getResourceAsStream("/" + PROCESS_DEF_XML));
        Element element = document.getRootElement();
        DefaultElement bpmToEsbVars = (DefaultElement) element.element("start-state").element("transition").element("action").element("bpmToEsbVars");

		String helloWorldTokenScope  = "Hello world token scope";
        String helloWorldGlobalScope = "Hello world process-instance scope";
        TestJBPMVariable objectTokenScope = new TestJBPMVariable("Object token scope") ;
        TestJBPMVariable objectGlobalScope = new TestJBPMVariable("Object global scope") ;

		Token token = processInstance.getRootToken();
        // Don't set v1, see what happens
        //processInstance.getContextInstance().setVariable("v1", helloWorldTokenScope, token);
        processInstance.getContextInstance().setVariable("g2", helloWorldGlobalScope);
        processInstance.getContextInstance().setVariable("h3", objectTokenScope, token);
        processInstance.getContextInstance().setVariable("i4", objectGlobalScope);
        ExecutionContext executionContext = new ExecutionContext(token);

        JBpmObjectMapper mapper = new JBpmObjectMapper();
        Message message = mapper.mapFromJBpmToEsbMessage(bpmToEsbVars, Boolean.FALSE, executionContext);

        assertEquals(helloWorldTokenScope,String.valueOf(message.getBody().get("esbObj1")));
        assertEquals(helloWorldGlobalScope,String.valueOf(message.getBody().get("esbObj2")));
        assertEquals(objectTokenScope.getInternal(), String.valueOf(message.getBody().get("esbObj3")));
        assertEquals(objectGlobalScope.getInternal(), String.valueOf(message.getBody().get("esbObj4")));
