我正在使用 Apache Gronimo 3.01，并且在使用基本身份验证的 Web 服务中发现了巨大的内存泄漏（如果不使用身份验证，则没有内存泄漏）：

唯一的代码就是这样：

 package org.apache.geronimo.samples.jws;

import javax.annotation.Resource;
import javax.jws.WebService;
import javax.xml.ws.WebServiceContext;

@WebService(serviceName = "Calculator",
            portName="CalculatorPort",
            endpointInterface = "org.apache.geronimo.samples.jws.Calculator",
            targetNamespace = "http://jws.samples.geronimo.apache.org"
            )
public class CalculatorService implements Calculator {

    @Resource
    private WebServiceContext context;

    public int add(int value1, int value2) {
        System.out.println("User Principal: " + context.getUserPrincipal());
        return value1 + value2;
    }
}

和

package org.apache.geronimo.samples.jws;

import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.WebParam;

@WebService(name="CalculatorPortType",
            targetNamespace = "http://jws.samples.geronimo.apache.org")
public interface Calculator {

    @WebMethod
    public int add(@WebParam(name = "value1") int value1,
                   @WebParam(name = "value2") int value2);

}

以及以下 XML：

        </sec:role-mappings>
    </sec:security>
</app:application>

在 geronimo 的控制台中，我设置了一个安全领域：LeakyWsSecurityRealm，它是一个“属性文件领域”。

问题是它泄漏对象，正如我在使用 VisualVM 时看到的，类型为“java.security.AccessControlContext”（OutOfMemoryError 之前的 128K 实例）被 64K 实例“org.apache.geronimo.security.Context”引用。

有人知道这里出了什么问题吗？
