Trying to serialization sequence coroutine state with Java Serialization

SequenceSerializationTest.kt

import java.io.*

fun main() {
    // test sequence -- 15 fibonacci numbers
    val seq = sequence {
        var prev = 0
        var cur = 1
        repeat(15) {
            yield(cur)
            cur += prev.also { prev = cur }
        }
    }
    // update its state
    val original = seq.iterator()
    println("Iterate first 5")
    repeat(5) {
        println(original.next().toString().padStart(10))
    }
    println("Serializing...")
    // serialize bytes
    val bytesOutput = ByteArrayOutputStream()
    val output = ObjectOutputStream(bytesOutput)
    output.writeObject(original)
    val bytes = bytesOutput.toByteArray()
    println("Got ${bytes.size} bytes: ${bytes.joinToString("") { it.toUByte().toString(16).padStart(2, '0') }}")
    // deserialize bytes
    val input = ObjectInputStream(ByteArrayInputStream(bytes))
    val result = input.readObject() as Iterator<*>
    // test the result
    println("Iterate the rest of deserialized iterator, size-by-side with original one")
    println("${"original".padStart(10)} ${"result".padStart(10)}")
    do {
        val originalNext = if (original.hasNext()) original.next() else null
        val resultNext = if (result.hasNext()) result.next() else null
        println("${originalNext.toString().padStart(10)} ${resultNext.toString().padStart(10)}")
    } while (originalNext != null || resultNext != null)
