... as well as $SwitchMap and other synthetic classes generated by javac or other JVM language compilers or runtimes. Note that for Kotlin, all synthetic classes were already handled by the subsequent check for `KotlinClassHeader.Kind.SYNTHETIC_CLASS`, but after this change we won't call `ReflectKotlinClass.create` for those, which is a minor optimization. #KT-41373 Fixed
