Hi, in this piece of code, I'm mocking a JDBC `ResultSet`, and therefore its `getLong()` method returns a JVM platform type (i.e. it could be `Long` or `Long?`):
```val id: Long? = &lt;...&gt;
every { resultSet.getLong("id") } returns id```
Unfortunately, this results in the error message "Type mismatch: inferred type is Long? but Long was expected." Is this a bug, a known limitation, or something I'm doing wrong? I can work around it like this:
```every { resultSet.getLong("id") as Long? } returns id```
but then IntelliJ IDEA warns me that `as Long?` is unnecessary.

I think the problem may actually be the opposite of what you describe. `getLong` returns a primitive `long`, so it can never be null. Your id is defined as `Long?`, which is nullable, so it can't be used as a return value for `getLong`.

Indeed, you're right, Sam. My mistake. Thanks.
