Personal preference and you don't have to do it, but catching all and then
checking the type reads nicer to me, compared to checking an integer.

+    i = 1;
+  }
+  Expect.equals(1, i);
+  try {
+    new A();
+  } catch (NoSuchMethodException e) {
+    i = 2;

ditto

+  }
+  Expect.equals(2, i);
+}
