kotlinlang

Hey guys I just encountered a weird bug(?) when using `Map.forEach` in Android. The reported exception is
`java.lang.NoClassDefFoundError  com.example.packagename.AdManager$executeQueuedCalls$1`
I found the solution on :stackoverflow: already, <https://stackoverflow.com/a/51215937/7684435>

My code looked like this before the fix: `grouped.forEach { type, interactions -&gt; TODO("placeholder") }`, and the kotlin compiler chose the `Map.forEach(BiConsumer&lt;? super K, ? super V&gt; action)` , which uses `java.util.function.BiConsumer` which isn't available on Android &lt; 8 Oreo.
Occured with kotlin version 1.2.30, also with 1.2.61, using this gradle config: `implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"`

I am not sure if this would be considered a bug or not
