Java Eclipse for OSGi框架中出错（BundleException:org.Eclipse.actf.model.internal.flash.proxy.ProxyPlugin.start中的异常）

以下是有关我正在使用的环境的详细信息：

-面向Java开发人员的Eclipse IDE（版本：Luna Service Release 1（4.4.1）） -Windows 7专业服务包1

-32位操作系统 我为Java开发人员安装了EclipseIDE（版本：Luna Service Release1（4.4.1）），我还使用IDE的“安装新软件”功能来获得“插件开发”模块

基本上，我尝试使用OSGi框架标准。 它是一个简单的Java应用程序，声明了“Hello World”，需要打包

package com.javaworld.sample.HelloWorldThree;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class Activator implements BundleActivator {

/*
 * (non-Javadoc)
 * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext)
 */
public void start(BundleContext context) throws Exception {
    System.out.println("Hello World!!");
}

/*
 * (non-Javadoc)
 * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext)
 */
public void stop(BundleContext context) throws Exception {
    System.out.println("Goodbye World!!");
}

}

这是我的清单。MF：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: HelloWorldThree
Bundle-SymbolicName: com.javaworld.sample.HelloWorldThree
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: com.javaworld.sample.helloworldthree.Activator
Bundle-Vendor: JAVAWORLD
Import-Package: org.osgi.framework;version="1.3.0"

遗憾的是，我得到了以下错误：

请告诉我如何解决上述错误。

提前感谢。

日志似乎是Eclipse ACTF的问题，与您的插件无关。我是否应该删除“Eclipse ACTF”插件以停止错误？我对ACTF一无所知，但这听起来是个合理的想法。
