com.typesafe.akka:akka-cluster-sharding_2.12:2.5
akka.cluster.sharding.ClusterSharding has the following methods:
public static ClusterSharding get(ActorSystem var0) {
return ClusterSharding$.MODULE$.get(var0);
}
public static Extension get(ActorSystem var0) {
return ClusterSharding$.MODULE$.get(var0);
}
NB: ClusterSharding <: Extension
None of these methods is synthetic or something, but javac allows
calls like ClusterSharding.get(null) and they get resolved
to the first method returning ClusterSharding
It seems that both javac and IntelliJ resolution algorithms filter out
such clashing declarations choosing the one that has the most
specific return type, the same idea is applied in the change

Also add a findInnerClass method that can find an inner class
by its name
This change helps to avoid loading all the inner class files
eagerly (that may be rather slow), while all the names are available
in InnerClass attribute
The reason is that canonicalText requires some additional
computations to be done when reading class files, while
in fact we only need a class name of the type
Searching for the single abstract method leads to computing
whole member scopes of given intrefaces, especially when
they contain a lot of methods (i.e. they're definitely not SAMs)
On the other side this method is very hot because it's called
for each Java interface used as a type for some value parameter
(for building SAM adapters)
The idea is to apply some heuristics to understand using only
JavaMethod and supertypes that this interface is definitely not a SAM
This fixes KT-17001 because now 'header' modifier is loaded correctly
for deserialized members and the standard disambiguation in
OverloadingConflictResolver.compareCallsByUsedArguments takes place,
where header members are discriminated against the corresponding impl
members
#KT-17001 Fixed
See how we translate raw types to Kotlin model:
RawType(A) = A<ErasedUpperBound(T1), ...>
ErasedUpperBound(T : G<t>) = G<*> // UpperBound(T) is a type G<t> with arguments
ErasedUpperBound(T : A) = A // UpperBound(T) is a type A without arguments
ErasedUpperBound(T : F) = UpperBound(F) // UB(T) is another type parameter F
Stack overflow happens with the following classes:
class A<X extends B> // NB: raw type B in upper bound
class B<Y extends A> // NB: raw type A in upper bound
when calculating raw type for A, we start calculate ErasedUpperBound(Y),
thus starting calculating raw type for B => ErasedUpperBound(X) => RawType(A),
so we have SOE here.
The problem is that we calculating the arguments for these raw types eagerly,
while from the definition of ErasedUpperBound(Y) we only need a type constructor
of raw type B (and the number of parameters), we don't use its arguments.
The solution is to make arguments calculating for raw types lazy
#KT-16528 Fixed
The main problem here is that moduleName that is being passed to KPackageImpl
is useless: as can be seen in
ClosureCodegen.generateCallableReferenceDeclarationContainer, the name of the
current module is always written to the class file for a callable reference,
not the name of the module of the referenced declaration. This resulted in
reflection not loading the correct .kotlin_module file and subsequently not
finding the required file facade for a top-level function.
The commit does not fix the issue with the incorrect module name written in the
back-end, but workarounds it. It turns out, reflection can figure out the name
of the module of the referenced declaration itself by parsing the header from
the given java.lang.Class object for a single-file/multi-file package facade
and extract the package_module_name protobuf extension. Similar code was
already there in Member.getKPackage() in ReflectJvmMapping.kt but it did not
support multi-file classes, of which there are a lot in the standard library;
this is now supported

A lot of problem arise with current solution
(loading them with lowpriority annotation + additional call checkers):
- We errorneously treated ArrayList.stream as an existing method, while
it's just a fake override from List
- The same problem arises when creating a class delegating to List.
Also the latter case is failing with codegen internal error
(see issue KT-16171)
The negative side of this solution is that instead of reporting meaningful
diagnostic, there will be UNRESOLVED_REFERENCE.
But it seems to be better than having strange problems like ones described above.

Since now `suspend (Int) -> String` will be serialized as `(Int, Continuation<String>) -> Any?` + suspend flag.
Before this change such type serialized like this: Function2<Int, String> + suspend flag. And yes, type `Function2<Int, String>` isn't correct, because Function2 expect 3 type arguments.
We have special logic for this case and we deserialize such error-written types correctly.

For sdkModule we create builtIns with default language feature settings.
Also when we create sdkModuleResolverProvider we create builtIns cache.
Then for every other module we get builtIns cached by value isAdditionalBuiltInsFeatureSupported.
Also move internal declarations from runtime.jvm module into new package
kotlin.coroutines.jvm.internal in stdlib
The necessity of these declarations being in built-ins is controversial,
but also it will complicate the migration of current coroutine runtime
to a separate jar if we ever need this
Inferred type of receiver of orElse is Optional<T & Any>
Generic descriptor is orElse(E!): E!
Substituted descriptor is orElse(T): T , and that is the problem.
Seems that E! => (T & Any)! gets expanded to just T or T & Any , however it should be expanded to
(T & Any) .. (T & Any)? => T & Any .. T & Any
T & Any is NotNullTypeParameter(T)
The problem is that (T & Any)? is expanded to T & Any,
that is seems to be wrong.

- calls must be prohibited iff they refer to some additonal built in member
- override must be prohibited iff all of the overridden descriptors are additional
Other usages were able to be successfully compiled by 1.0.x
Solution with @Deprecated(level=Error) doesn't work properly, because
deprecation propagates to overridden, thus call 'java.util.ArrayList<String>().stream()'
becomes invalid, while it was correct in 1.0.x
#KT-15794 Fixed
This is needed because 1.1.2 binaries are considered pre-release (see
DeserializedDescriptorResolver), so it wasn't possible to compile
non-pre-release binaries with -language-version 1.0
The -Xskip-metadata-version-check command line argument is supposed to be used
to avoid getting errors only; the side effect that it also caused compiler to
write the pre-release flag to binaries was a mistake and is fixed now
We made it because of non-stable name resolution when project is multi platform. For such projects in platform module we have two classifiers with the same name, but impl class or type alias should win!
