Paul Merlin commented on ZEST-122:
----------------------------------
It turns out that parameter names are not included in bytecode by default.
One need to compile using {{-parameter}}.
So this issue is more about supporting parameter names when they are enabled
and falling back to previous behaviour if not.
> Use parameter names to build better error messages on null barrier faults

>
> Parameters to composite's methods must be non-null by default. This can be
> relaxed using the @Optional annotation.
> This issue is about producing more meaningful error messages, ie. including
> the parameter name, when a null parameter is given to a composite's method.
