1. Scheme of capturing local variables not touched
2. Lowered local functions are transposed to the nearest class (including local) or file
3. Local classes are also transpose to the nearest class (including local) or file
The comment in the code is correct that EnclosingMethod
attributes should only be generated for local and
anonymous classes. We were generating them for member
classes as well which leads to invalid class files.
With this change I had to mute one more tests. That is
because we lose the parent method and therefore we
see a class as a member class instead of a local class.
With the old descriptor based check that test still
passes.
Current implementation of calls with super qualifier relies on
invokespecial, which has some more constraints than regular virtual
invocations. When those constraints aren't met, accessors are needed.
This works in many cases, however, it is incomplete since there
are cases where classes are extracted to top-level and therefore
reparented. Therefore, we lose the information about the function
class are nested inside.
In JDK 9, Class.simpleName changed behavior for local/anonymous Kotlin
classes (see KT-23072), this is why we now check for both variants of
the name in tests. Also, the format of annotation arguments changed a
little, where float parameters no longer have the trailing "f", and
class literals are rendered with ".class" at the end
Codegen generates static backing fields for object properties.
They are initialized in class constructor but some of them are final static
and such access is prohibited in specification but it's allowed in
java bytecode <= 1.8. Such access in 1.9 bytecode cause
"IllegalAccessError: Update to static final field Object.INSTANCE
attempted from a different method (<init>) than the initializer method <clinit>"
Added additional hidden field in interface companion to pass out
companion instance from <clinit>.
#KT-15894 Fixed
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.
