在停止OSGi框架之前，如何銷毀所有OSGi藍圖組件？

Question

如果我停止OSGi框架，則不會破壞OSGi藍圖組件（不會調用銷毀方法）。 為什么會這樣，我如何銷毀它們。 我有自己的OSGi啟動器實現。 我正在使用關閉鈎子，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);
            }
        }
    }
});

我們應該等待框架停止。

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);
            }
        }
    }
});
