We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
The current implementation doesn't consider Foo a subtype of Captured<in
Foo>!!, since AbstractTypeCheckerContext::checkSubtypeForSpecialCases
does not handle DefinitelyNotNullType cases. This PR adds handling of
DefinitelyNotNullType by looking at its original type.
^KT-42824 Fixed
The issue is the type checker doesn't consider P? a subtype of
CapturedType<in P>?, whereas P a subtype of CapturedType<in P>?. In
AbstractTypeCheckerContext::checkSubtypeForSpecialCases, it checks if
P? is a subtype of the lower type of the captured type, which is
P, and returns false.
This fix uses nullable version of the lower type when the captured
type is marked nullable. To check if P? is a subtype of Captured<in
P>?, we check the LHS, P?, against the nullable lower type of RHS,
P?.
^KT-42825 Fixed
'descriptor -> descriptor.original' relation is often inconsistent
wrt 'containingDeclaration', parameters, and type parameters,
we have to introduce some workarounds here.
This patch mutes the following test categories:
* Tests with java dependencies (System class,
java stdlib, jvm-oriented annotations etc).
* Coroutines tests.
* Reflection tests.
* Tests with an inheritance from the standard
collections.
