Need to figure out how many cases there are, and whether it is all handled by the same piece of code.

> Key: POLYGENE-122
> URL: https://issues.apache.org/jira/browse/POLYGENE-122
> Project: Polygene
> Issue Type: Improvement
> Reporter: Paul Merlin
> Priority: Major
> Fix For: 3.1.0
>
>
> 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.
> See https://docs.oracle.com/javase/tutorial/reflect/member/methodparameterreflection.html for details on parameter names reflection.
