Is this file related to factory change?

No, but this test was mixed with upper bounds tests in
tests/language/src/TypeVariableBoundsTest.dart.
It is better to make it a separate test.

+class FBound<F extends FBound<F>> {}
+
+class Bar extends FBound<Bar> {}
+
+class SubBar extends Bar {}
+
+main() {
+  FBound<Bar> fb = new FBound<Bar>();
+  FBound<SubBar> fsb = new FBound<SubBar>();  /// 01: static type error
+}
