问题描述
我正在尝试从运行在Jetty容器（jetty-distribution-9.4.32.v20200930）中的Web应用程序初始化Okhttpclient。如果我使用OkHtp 3.X（3.14.9），一切运行正常。升级到OkHttp 4.9.0（OkHttp 4.X将实现语言从Java更改为Kotlin）后，我的应用程序无法启动，并出现以下错误：

观察
- 我只有在使用Jetty时才能得到它。如果我使用Tomcat 8.5，则无法运行 进入这个stackoverflow。
- 这只会在我打电话时发生 OkHttpClient.Builder（）。如果我不使用生成器并实例化它 使用新的OkHttpClient（），我不会遇到stackoverflow。
- 我正在使用Xss256k而不是默认的1024k。只是撞上我 stacksize为278k似乎可以解决此问题。但是，这取决于 在OS上。在Debian 9中，278k是较低的阈值。在我本地 运行macOS mojave的计算机可以用258k弥补。
我相信发生这种情况是因为码头正在加载kotlin编译的类并通过递归调用查找它们，堆栈越来越大，最终达到了256k的限制。尽管我通过提高Xss来解决它，但是我发现这种行为很奇怪。因此，感谢您的评论。
