Exception is thrown when parsing the following code:

class FilteringExecutor(
    private val delegate: ExecutorService = Executors.newSingleThreadExecutor()
) : Executor {
    var filterFunction: (Runnable) -> Boolean = { true }
        // failing expression
        set(value) {
            field = value
            reEnqueueDeferred()
        }
        // failing expression

    private fun reEnqueueDeferred()  {}
}

It appears that accessor.stub can be null with 2.0.20.

Full exception:
