it might be good to be more specific: duplicate declaration of variable "e" in
catch clause in method Helper.f1().

 interface TestException {
   String getMessage();
 }
 
 class MyException implements TestException {
-  const MyException(String message = "") : message_ = message;
+  const MyException([String message = ""]) : message_ = message;
   String getMessage() { return message_; }
   final String message_;
 }
 
 class StackTrace {
-  StackTrace() { }
 }
 
 class Helper {
   static int f1(int i) {
     try {
       int j;
       j = f2();
       j = f3();
     } catch (TestException e, StackTrace e) {
       i = 200;
     }
     return i;
   }
 
   static int f2() {
     return 2;
   }
 
   static int f3() {
     int i = 0;
     while (i < 10) {
       i++;
     }
     return i;
   }
 }
 
-class TryCatch3NegativeTest {
-  static testMain() {
-    Expect.equals(1, Helper.f1(1));
-  }
-}
-
 main() {
-  TryCatch3NegativeTest.testMain();
+  Expect.equals(1, Helper.f1(1));
 }
