我正在编写一个部署在 tomcat 上的 web 服务，当客户端调用 web 服务时，它设法成功发送信息，但是当我应该得到回复时，我在控制台中收到如下错误消息我确实注意到 tomcat 崩溃并关闭，每次我运行客户端时，我都必须再次启动 tomcat

SEVERE: The web application [/axis2] is still processing a request that has yet to finish. This is very likely to create a memory leak. You can control the time allowed for requests to finish by using the unloadDelay attribute of the standard Context implementation.

我无法判断服务的逻辑是否损坏，或者设置是设置不正确，但我得到的印象是服务无法找到发送请求的客户端
这可能是由外部库引起的吗？我使用刚刚放在 webapps\axis2\WEB-INF\lib 文件夹中的 bouncycastle 库
我在 webapps\axis2\WEB-INF\classes 中还有一个属性文件和一个 jaas 配置文件，我按如下方式访问它们
属性文件
Properties props = new Properties();
props.load( new FileInputStream( "C:\\apache\\apache-tomcat-7.0.29\\webapps\\axis2\\WEB-INF\\classes\\server.properties"));
JAAS 配置文件
System.setProperty( "java.security.auth.login.config", "C:\\apache\\apache-tomcat-7.0.29\\webapps\\axis2\\WEB-INF\\classes\\jaas.conf");
