That is wrong all, non annotated Java code gets a special type denoted with a ! . You can use ?. or assign it to a new val with ?: return.

Or you throw all the null safety away and write unsafe java code but in Kotlin the same as the Java code you're working with.

You can use ?. or assign to a nullable type. Or you can get a NPE at runtime. Which is to say, it's not null-safe.

So you're in the exact same case as you were in Java, which was my third point. But the type is a special type to let you know what you're doing is unsafe.
