corda - 节点驱动程序挂起并超时

运行简单的节点驱动程序时，NodeDriver有一个我从未见过的问题:

fun main(args: Array<String>) {
    val rpcUsers = listOf(User("user1", "test", permissions = setOf("ALL")))

    driver(DriverParameters(startNodesInProcess = true, waitForAllNodesToFinish = true)) {
        startNode(providedName = CordaX500Name("PartyA", "London", "GB"), rpcUsers = rpcUsers).getOrThrow()
        startNode(providedName = CordaX500Name("PartyB", "New York", "US"), rpcUsers = rpcUsers).getOrThrow()
    }
}

当我在新的Kotlin模板cordapp项目中使用Corda OS 4.1运行它时，它可以正常工作。
但是，当它在我们现有的cordapp中运行时，它最终会失败并显示以下内容:

java.lang.IllegalStateException: Unable to start notaries. A required port might be bound already.

对此进行调试，当我在阻止它的过程中断点时，所有线程都处于WAIT状态，除了称为SignalDispatcher的一个RUNNING之外。 Corda中都没有堆栈。但是，某些类在Quasar堆栈中处于阻塞状态。

进一步调试，我发现了发生阻塞行为的行:net.corda.node.services.rpc.ArtemisRpcBroker.kt:74

val serverConfiguration = RpcBrokerConfiguration(baseDirectory, maxMessageSize, jmxEnabled, addresses.primary, adminAddressOptional, sslOptions, useSsl, nodeConfiguration, shouldStartLocalShell)

进入该构造函数后，Quasar接管并似乎反复调用ClassLoader.checkPackageAccess。允许 call 继续，它永远不会输入RpcBrokerConfiguration#init。

之前是否有其他人看到过这种情况，是否有解决此问题的建议或关于如何进一步调试的线索？谢谢。

PS-此引用Corda errorCode 1crywct。

最佳答案

FWIW，我将检查使用相同端口的其他进程，或者仅通过节点驱动程序更改端口。例如，Intellij随附的YourKit默认在端口10001上运行，即在默认的节点驱动程序公证端口上运行-好吧，假设我没记错的话。
