When using `lateinit var` on the JVM on a field on an object used from more than one thread do you also need `@Volatile` to prevent other threads seeing it as null, or do you get that for free?

Should have done this before asking… viewing &amp; decompiling the bytecode shows that no, you do not get `@Volatile` for free, so if you want to use a `lateinit var` field in a class that will be used from multiple threads you need to mark it as `@Volatile` manually.
