Found when fixing JDK-8224110:

public class VarArgsArray {

  inline class MyInt {
    int value;
    public MyInt() { this(0); }
    public MyInt(int v) { this.value = v; }
  }

  public VarArgsArray() throws Throwable {
    MyInt[] a = new MyInt[0];
    this.getClass().getDeclaredMethod("test", MyInt[].class).invoke(this, a); // <--- Warns, but in the case of known inline type, should be error
  }

  public void test(MyInt[] a) {
    System.out.println(a);
  }

  public static void main(String[] args) throws Throwable {
    new VarArgsArray();
  }
}
