      Code excerpt from Demo project based on Kie/Drools Sample projects & code:

      	final DemoData scanResult = new DemoData("DemoData1", "KieIssueDemo", "Demos", Arrays.asList("Demo Rule 1"),
		"Inventory Item 001");
	@SuppressWarnings("unchecked")
	Command<DemoData> insert = commandsFactory.newInsert(scanResult);
	Command<?> fireAllRules = commandsFactory.newFireAllRules();
	Command<?> batchCommand = commandsFactory.newBatchExecution(Arrays.asList(insert, fireAllRules));

	ServiceResponse<ExecutionResults> executeResponse = rulesClient.executeCommandsWithResults(containerId,
		batchCommand);

      Demo project showing this issue with output will be attached.
