A DESCRIPTION OF THE PROBLEM :
The Java Language Specification (and javac) currently permits using an array creation expression (in the form ComponentType[]::new) as method reference expression for methods of functional interfaces with return type `void`.

This is inconsistent with lambda expressions which explicitly require a StatementExpression (which ArrayCreationExpression is not).

// As expected: Causes compiler error
Consumer<Integer> c = i -> new int[i];

// Unexpected: Does not cause compiler error
Consumer<Integer> c = int[]::new;
