In my KMP project, after upgrade to Kotlin 1.6.20, I see this error in IntelliJ only (no error when building from gradle). Is this correct behavior?

Which Exception are you importing in ServiceException?

I'm not importing anything, so I assume it is

kotlin.Exception

Try extending java.lang.Exception instead

It's common code. I can't use java.lang.*

Ah try

e: java.lang.Exception

?

The same error just a bit different message

Incompatible types: ServiceException and Exception
