EVALUATION Interesting corner case: class Test { interface A {} interface B extends A {} Test(A... args) {} Test(A a, A... args) {} void test(B b) { new Test(b); } } What should we do with it? JLS seem to be for giving ambiguity here, but I think there's evidence that the second signature is most specific as it requires at least one mandatory argument.
