In many other places, e.g. org.jetbrains.kotlin.codegen.ClassBodyCodegen#generateDelegatesToDefaultImpl we implicitly assume that whenever we use a default interface method our target is 1.8 But here, we don't and it might lead to exception in org.jetbrains.kotlin.backend.common.bridges.BridgesKt#findConcreteSuperDeclaration when actual target is 1.6 and we extend some AbstractMap implementation with JDK8 (i.e., with @PlatformDependent getOrDefault)
