| * @assertion CONST_CANONICAL_TYPE(C<T0, ..., Tn>) = C<R0, ..., Rn>* |
| * where Ri is CONST_CANONICAL_TYPE(Ti) |
| * Note this includes the case of an interface type with no generic parameters |
| * (e.g int). |
| * |
| * @description Checks that CONST_CANONICAL_TYPE(C<T0, ..., Tn>) in the weak |
| * mode. |
| * Please note that this test should not be executed with analyzer. |
| * The exception is that some constant expressions are evaluated at compile time |
| * (we don't actually promise that they are evaluated before run time, but we |
| * know that some compile-time evaluation does take place); some of those |
| * constant expressions have different semantics in an execution with sound and |
| * unsound null checking. Hence we may be able to observe a different behavior. |
| * The analyzer assumes sound null checking during constant evaluation. So, the |
| * test should be skipped by analyzer. |
