What steps will reproduce the problem?

1. Check out this file:
   https://code.google.com/p/dart/source/browse/branches/bleeding_edge/dart/utils/tests/string_encoding/dunit.dart
2. On line 116:
   void registerTests(TestSuite suite);
3. That method has no body and it's not an abstract class.

What is the expected output? What do you see instead?
I expect the method to have a body like so:
void registerTests(TestSuite suite) { }
