Параллельный поток Kotlin/Java в виртуальных потоках

Question

У меня есть проект на Котлине с Java 19 (с экспериментальными функциями). У меня есть код:

      private val virtualExecutor = Executors.newVirtualThreadPerTaskExecutor()


private fun countTenantsConsumption(
        paged: Page<Tenant>,
        command: RequestCommand
    ): List<TenantConsumption> {
        val callable = Callable {
            paged.payload!!.parallelStream()
                .map { Pair(it, callForTenantData(command.tenantDataCommand(it))) }
                .map { TenantDataProcessor(it.first, it.second, factorService).process() }
                .collect(Collectors.toList())
        }

        return virtualExecutor.submit(callable).get()
    }

и я функционируюcallForTenantDataимеет регистратор внутри:

      private fun callForTenantData(readingCallCommand: ReadingCallCommand): List<PeriodDeviceReading> {
        val start = System.currentTimeMillis()
        val data = //call for data
        logger.info("Loading data on ${Thread.currentThread().threadId()}, virtual: ${Thread.currentThread().isVirtual} took: ${System.currentTimeMillis() - start}ms")
        return data
    }

и я получаю вывод:

Только первый элемент в потоке обрабатывается виртуальным потоком. Почему ? Как исправить это для обработки всего потока в виртуальных потоках?
