java - Tomcat 在未部署时抛出严重警告

Question

Tomcat版本:7.0.41(也试过8.0.32)
JRE: 6u42
编写了一个非常简单的 JAX-WS 应用程序(作为测试)。当使用“?wsdl”时，应用程序目前只显示 wsdl 文件，当给出 SOAP 请求时，我只是返回一个字符串。

@WebService
public class SOAPWithWS
{
    @WebMethod
    public String HelloTest(String sMessage)
    {
        return "Received : " + sMessage;
    }
}

当我尝试取消部署上下文时，它会给我如下警告:

每次我测试时都会发生这种情况。 GlassFish 服务器上不会发生同样的情况(只是试图测试这种情况)。知道发生了什么以及如何消除这个问题吗？

您的应用程序存在内存泄漏。检查此主题，它可能会有所帮助；
