| // Test that we don't crash on computing js-interop classes when metadata |
| // constants contain implicit casts. |
| // |
| // We need the class hierarchy to perform the evaluation the implicit casts but |
| // we also change the class hierarchy when we discover that a class is a |
| // js-interop class. By mixing (valid) constants that contain implicit casts |
| // with the @JS annotations that define classes to be js-interop, triggering |
| // the use of the class hierarchy before all js-interop classes have been |
| // registered, this test causes dart2js to crash with an assertion failure. |
