# serialization

[Amaan]

The smallest reproducible version of the problem I'm having is this:

@Serializable
open class Box<T>(val contents: T)

@Serializable
class StringBox(
    private val data: String
) : Box<String>(data)

fun main() {
    println(
        Json.encodeToString(
            StringBox("Kotlin")
        )
    )
}

and I still get a java.lang.IndexOutOfBoundsException. Is this a bug in the serialization compiler code?
