Hey @Łukasz Gendek,
That's strange. 🤔 Can you share your gradle file, so I can try reproducing this locally?

[Łukasz Gendek]

here you go

build.gradle

[Łukasz Gendek]

Hey. I just want to ask, if you were able to reproduce this?

[simon.vergauwen]

Hey @Łukasz Gendek,
Yes, I am able to reproduce this. First moment I had free to check this, thanks for you reminder.

That is definitely a bug.. I think it's a combination of inline and private, which shouldn't have been allowed but somehow the compiler didn't complain 🤔

[simon.vergauwen]

Thanks for sharing the Gradle config, made it easy to reproduce. Silly thing is we cannot write a test for this in Arrow since it requires being called from a different compilation unit 🙃

[Łukasz Gendek]

It is interesting that this works when moving the code to the arrow.core.raise package.

[Łukasz Gendek]

So I have a workound.

[Łukasz Gendek]

But still I can't wait till it gets fixed and I would not need the workaround :)
