A Thing… parameter can be passed to a method expecting a Thing … or Thing argument. However, you can’t pass it to a method expecting an Iterable<? extends Thing>. You must convert it to an explicit Iterable, usually with Arrays. asList( ).
An array is not a true Iterable. It does not have a iterator method. The compiler treats it as Iterable in for:each, but does not use an Iterator; it fudges a traditional for loop.
If you need a constructor with two … parameters, handle one in the constructor, and the second in a setter invoked in a static init block.
