为什么 AsyncHttpClient 在抛出异常后不关闭线程？
Why doesn't AsyncHttpClient close the thread after throwing an exception?
我正在使用 Zendesk Java Client。当我提供正确的凭据时，它会按预期工作。但是，我偶然发现了一个场景，如果传入了错误的凭据，线程就会挂起并抛出错误。无论我 运行 使用或不使用调试器的代码，代码都保持 运行ning。它不会退出或 return 控制给调试器。
这是库的问题，还是我误解了 AsyncHttpClient 的工作原理？
我的代码如下：
fun zdtestWrongCredentials() {
val client = asyncHttpClient(
config()
.setRequestTimeout(5000)
.setReadTimeout(5000)
.setShutdownTimeout(3000)
.setPooledConnectionIdleTimeout(5000)
.setKeepAlive(false)
)
var zd = Zendesk.Builder("https://website.zendesk.com")
.setClient(client)
.setUsername("john.doe@website.com")
.setPassword("abcd")
.build()
var ticket = Ticket(123, "a", Comment("abc"))
// The code hangs here. It's unclear why it exhibits this behavior.
var test = zd.createTicket(ticket)
// The code does not reach this line.
client.close()
return
}
虽然我使用的是 Kotlin，但我尝试在一个简单的 Java 项目中复制这个问题，但问题仍然存在。
堆栈跟踪如下。底部有一个异常，但即使在这个异常之后，程序也没有exit/give将控制权交还给调试器。

根据异步客户端的实现方式，它可以在一个 thread/coroutine 中抛出错误，然后等待完成消息或在其代码的另一部分触发。
由于抛出了错误，触发器从未发送，因此线程永久挂起。
我"built"遇到过一次这样的问题，所以是的，这是可能的。
显然，我不知道这是否真的是手头的问题。
干杯，祝一切顺利！
我正在使用 Zendesk Java Client。当我提供正确的凭据时，它会按预期工作。但是，我偶然发现了一个场景，如果传入了错误的凭据，线程就会挂起并抛出错误。无论我 运行 使用或不使用调试器的代码，代码都保持 运行ning。它不会退出或 return 控制给调试器。
这是库的问题，还是我误解了 AsyncHttpClient 的工作原理？
我的代码如下：
fun zdtestWrongCredentials() {
val client = asyncHttpClient(
config()
.setRequestTimeout(5000)
.setReadTimeout(5000)
.setShutdownTimeout(3000)
.setPooledConnectionIdleTimeout(5000)
.setKeepAlive(false)
)
var zd = Zendesk.Builder("https://website.zendesk.com")
.setClient(client)
.setUsername("john.doe@website.com")
.setPassword("abcd")
.build()
var ticket = Ticket(123, "a", Comment("abc"))
// The code hangs here. It's unclear why it exhibits this behavior.
var test = zd.createTicket(ticket)
// The code does not reach this line.
client.close()
return
}
虽然我使用的是 Kotlin，但我尝试在一个简单的 Java 项目中复制这个问题，但问题仍然存在。
堆栈跟踪如下。底部有一个异常，但即使在这个异常之后，程序也没有exit/give将控制权交还给调试器。

根据异步客户端的实现方式，它可以在一个 thread/coroutine 中抛出错误，然后等待完成消息或在其代码的另一部分触发。
由于抛出了错误，触发器从未发送，因此线程永久挂起。
我"built"遇到过一次这样的问题，所以是的，这是可能的。
显然，我不知道这是否真的是手头的问题。
干杯，祝一切顺利！
