与Kotlin协程的操作数堆栈上的错误类型

Question

此代码与Kotlin 1.2.10成功编译，但是当我运行它时会生成java.lang.VerifyError: Bad type on operand stack。如果我删除Test类并提取函数，它将按预期工作。那是为什么？

import kotlinx.coroutines.experimental.delay
import kotlinx.coroutines.experimental.launch
import kotlinx.coroutines.experimental.runBlocking
import java.util.*
import kotlin.concurrent.schedule

class Test {
    fun scheduleTimeout() {
        Timer(true).schedule(300) {
            launch {
                runSuspended("hello")
            }
        }
    }

    suspend fun runSuspended(txt: String) = println(txt)
}

fun main(args: Array<String>) {
    Test().scheduleTimeout()
    runBlocking {
        delay(10000)
    }
}

完全例外：
