logs would cause logs within method call to reference line num and method name 
of the parent method

>             Project: Log4j 2
>          Issue Type: Bug
>          Components: API
>    Affects Versions: 2.6.2

>            Priority: Minor

> While logging a message using lambda expressions. If i call a method within 
> the log message (i.e logger.info(() -> "foo" +bar()) which also logs 
> messages, those logs within the called method will reference the line number 
> and method name of the method which invoked it.
> Running the following code demonstrates this issue:
> {code:title=TestingLogging.java|borderStyle=solid}
>  private static final Logger LOGGER = 
> LogManager.getLogger(TestingLogging.class);
>     public static String foo(){
>         LOGGER.info("bar");
>         return "foo";
>     }
>     public static void main(String[] args){
>         System.out.println("correct method reference: ");
>         LOGGER.info(foo());
>         System.out.println("\nincorrect method reference: ");
>         // causes logging in foo to reference
>         // this line number and method (main)
>         LOGGER.info(() -> foo());
>     }
> {code}
