我遇到SSL连接问题，当一个方法在Tomcat 8实例中运行时，立即抛出一个 java.net.SocketException：Connection reset 但是当一个方法在同一个方法中运行时没有在IntelliJ IDEA中启动了jUnit测试。
我的猜测是这些执行的SSL上下文之间存在差异，但我无法弄清楚在哪里。
stacktrace：

如您所见，我们正在使用Microsoft adal4j身份验证库，它依赖于sun SSLSocket库。所以我没有完全控制代码，也没有完全控制这个库试图访问的URL，但是当我向那些带有随机HTTP客户端的URL发出GET请求时，我得到了一个成功的结果，所以我认为这不是由于远程服务器
另外，在两种情况下调试方法时，比较SSL相关类实例时，我找不到任何明显的差异。
所以我的问题是：
非常感谢！
编辑：以下是使用-Djavax.net.debug = all VM选项在Tomcat 8上运行代码时显示的SSL日志：
