Custom steps with integer argument is not working .

[khatriarpit]

Hello I am facing couple of problem .

I have created custom steps as below.

@QAFTestStep(description = "wait for {0} milisec")
public static void wait_for_milisec(Integer time) {
	 try {
		 Thread.sleep(time);
		} catch (Exception e) {
	    }
   }

Also my scenario file as below

@description:TestingJava Description Testing
Scenario: test
   Given get "http://www.demoqa.com/alerts"
   Then wait for 4000 milisec

I am getting error saying unimplemented method which is working fine if i change argument to String . Integer Argument create problem .
Also Second problem i am getting description as first word in report not whole line .Above test case it is printing Description as "TestingJava".
Could you please help ?
