// 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.
