JDK-8238213: javac emits wrong error when calling an non-static overloaded method from static

[B. Blaser]

Testing a few more, I note that a discrepancy with the JLS in this
area might have deeper consequences beyond wrong diagnostics,
consider:

public class Test {
  public static void main(String[] args) {
    test((Double)5.0);
  }

  void test(Number n) {
    System.out.println(Number.class);
  }

  static void test(Double... d) {
    System.out.println(Double.class);
  }
}

JDK16 currently resolves and runs 'test(Double...)' instead of raising
a static error as mandated by §15.12 and according to the suggested
fix.
I'm not sure where to find JDK7 x86_64 binaries, so maybe you could
try this one too and share your thoughts?
