> Exception message seems to be inexact. 
> Also if there is no SAM, sam would be null upon returning from the method.
> The suggestion from a review was to change the message and add a check (for null sam)
prior to returning.
> Another suggestion is to check if the given method is an interface, as only for interface
it is possible to pass lambda.
