A modern programming language that makes developers happier.

kotlinlang

Is this a bug:
```Compilation failed: Parameter specified as non-null is null: method kotlin.collections.CollectionsKt___CollectionsKt.joinToString, parameter $this$joinToString```
I haven't used joinToString in my project though this error comes in when I define a global variable:
```@SharedImmutable
private val globalVar: AtomicRef&lt;ObjectType?&gt; = atomic(null)```
:blob-thinking-upside-down:

Edit: Even with normal variable on top level scope this happens (also tested on `@ThreadLocal`).

Ohk, I've reproduced it, it was cuz of annotation. Reported: <https://youtrack.jetbrains.com/issue/KT-44007>
