[rabbitmq-discuss] How to check if custom headers attribute exist

[cw storm]

Please forgive me but I have a simple question.  How can I check to see if
there's custom header attribute exist or not before I perform the below:

String strFirstName = props.getHeaders().get("FirstName").toString()

I believe if there's no custom headers, then it'll exception.
