kotlinlang

Hello, everyone! :blush:

Is there a reason to the following code give me a Java warning?
I made it nullable because this is a non-required foreign key.

```internal inline class CategoryId(val value: Long?)```
```fun test(){
    CategoryId(12)
}```
Warning: `Use Long.valueOf(12) instead`

Weird… Maybe some config on my side.
I tried on Kotlin 1.4.30.

Even weirder is if I try to set null:
`Use Long.valueOf(null) instead`

```Kotlin: kotlinc-jvm 1.4.30 (JRE 11.0.5+10-LTS)
Kotlin: The feature "inline classes" is experimental```

Warning about `inline`, but nothing about `Long`. Must be somewhere else.

at least with 1.4.30, the kotlinc-jvm output will emit a `Long.valueOf(12)` call rather than `new Long(12)` (which is what that warning sounds to be about), so I don’t see where it’s coming from (tbh I can’t even tell what tool it’s coming from)
