hi folks, anyone knows why atomicFu raises an error here:

private class Node(
    val job: QueueJob,
    // Pointer to the next node in linked list.
    val next: AtomicRef<Node?> = atomic(null)
) {
    // Checks if this node is the physical tail of the linked list.
    val isTail: Boolean get() = next.value == null
}

Error:

Exception in thread "main" java.lang.NoSuchMethodError: 'void asynqueueproblem.Queue$Node.<init>(kotlin.jvm.functions.Function2, kotlinx.atomicfu.AtomicRef, int, kotlin.jvm.internal.DefaultConstructorMarker)'

It complains when i am creating an instance of Node .

[George]

If i change Node to something like this:

private class Node(
    val job: QueueJob,
    @Suppress("LocalVariableName") _next: Node? = null
) {
    // Pointer to the next node in linked list.
    val next: AtomicRef<Node?> = atomic(_next)

    // Checks if this node is the physical tail of the linked list.
    val isTail: Boolean get() = next.value == null

    fun setNext(newNode: Node) {
        while (true) if (next.compareAndSet(null, newNode)) return
    }
}

The error goes away.
