Previously, for a property named `x` in the companion object of a class named `Foo`, we generated: - `Foo.access$getX$cp`, consisting of `GETFIELD Foo.x` and lateinit assertion - `Foo.Companion.getX`, consisting of `INVOKEVIRTUAL Foo.access$getX$cp` Now, we generate: - `Foo.access$getX$cp`, consisting of `GETFIELD Foo.x` - `Foo.Companion.getX`, consisting of `INVOKEVIRTUAL Foo.access$getX$cp` and lateinit assertion The reason is that this way we can avoid generating another accessor and reuse `Foo.access$getX$cp` in case `isInitialized` is called on a lateinit property from companion. For private properties, getX is not generated, but instead the assertion is generated on each access to the field (which can be improved, see KT-28331). The same happens for access to non-private properties from inside the same context where they're declared. #KT-21862 In Progress
