Convert Comparable&lt;*&gt; but get error inferred type is Any? but Nothing was expected
I am trying to convert this piece of java code to kotlin
public int compare1(Comparable c, Object o) {
return c.compareTo(o);
}


to kotlin code:
fun compare1(c: Comparable, o: Any?): Int {
return c.compareTo(o)
}

But get error
Type mismatch: inferred type is Any? but Nothing was expected


Any reason why this error occurs? Thanks
