Question

如果我停止OSGi框架，则OSGi蓝图组件不会被破坏（不调用销毁方法）。为什么会这样，我如何销毁它们。我有自己的OSGi启动器实现。我正在使用关闭钩子，然后停止OSGi框架：

Runtime.getRuntime().addShutdownHook(new Thread() {
    @Override
    public void run() {
        Launcher.logService.log(LogService.LOG_WARNING, "HANDLE SHUTDOWN");
        if(Launcher.framework != null) {
            try {
                Launcher.framework.stop();
            } catch (BundleException e) {
                Launcher.logService.log(LogService.LOG_ERROR, "Shutdown" + ((Launcher.framework != null) ? " of " + Launcher.framework.getSymbolicName() + " " : " ") + "failed!", e);
                System.exit(-1);
            }
        }
    }
});

我们应该等待框架停止运行。

Runtime.getRuntime().addShutdownHook(new Thread() {
    @Override
    public void run() {
        Launcher.logService.log(LogService.LOG_WARNING, "HANDLE SHUTDOWN");
        if(Launcher.framework != null) {
            try {
                Launcher.framework.stop();
                Launcher.framework.waitForStop(0); // !!!
            } catch (BundleException e) {
                Launcher.logService.log(LogService.LOG_ERROR, "Shutdown" + ((Launcher.framework != null) ? " of " + Launcher.framework.getSymbolicName() + " " : " ") + "failed!", e);
                System.exit(-1);
            }
        }
    }
});

在停止OSGi框架之前，如何销毁所有OSGi蓝图组件？
