Two extensions, one JVM method

Kotlin sees two functions here. The JVM sees one:

fun ArrayList<SongsResult>.toListTrack(): ArrayList<Track> { … }
fun ArrayList<VideosResult>.toListTrack(): ArrayList<Track> { … }

An extension function compiles to a static method whose first parameter is the receiver, and a generic type's argument is erased on the way down. Both become toListTrack(ArrayList), and the compiler stops with a platform declaration clash, naming both declarations and the one signature they share.

One annotation on one of the two ends it:

import kotlin.jvm.JvmName
