OSGI框架中部署的每个捆绑包是否都有自己的bundleContext对象？

我对OSGI框架是完全陌生的，并且尝试通过以下两个捆绑包进行测试：

捆绑软件1：我使用工件组org.apache.karaf.archetypes通过maven创建了OSGI捆绑软件。在bundle 1激活器类中，我正在注册以下服务：

 public void start(BundleContext context) {
        System.out.println("-------------- Starting firstbundle ----------------");
        context.registerService(EmployeeService.class, new EmployeeServiceImpl(), null);
    }

软件包1的MANIFEST.MF文件的内容：

Manifest-Version: 1.0

Built-By: 212807091

Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"
Tool: Bnd-2.3.0.201405100607

捆绑软件2：我以创建捆绑软件1的相同方式创建了另一个独立的捆绑软件。捆绑软件2激活器类如下：

 public void start(BundleContext context) {
        ServiceReference<?>  ref = context.getServiceReference(EmployeeService.class);
        EmployeeService empService = (EmployeeService) context.getService(ref);
        boolean isRegister = empService.register("rohit", "rohit");
        if(isRegister){
            System.out.println("employee registered successfully");
        } else{
            System.out.println("employe is already registered");
        }
    System.out.println("after register employee list: "+empService.getEmployeeList().size());
    
}

软件包2的MANIFEST.MF文件的内容：

Manifest-Version: 1.0
Bnd-LastModified: 1594907276585

Export-Package: com.osgi.learn.secondbundle;version="0.0.1.SNAPSHOT";use

 2)"
Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"
Tool: Bnd-2.3.0.201405100607

现在我已经在OSGI环境中安装了两个捆绑软件，并且当我启动两个捆绑软件时，捆绑软件1已正确启动，而捆绑软件2则抛出如下错误：

osgi> ss

我有以下疑问：

1. 您能否让我知道为什么bundle 2无法部署以及如何解决它。

2. 每个捆绑程序Activator类对象是否获得唯一的BundleContext对象。如果是这样，那么一旦捆绑包将类对象注册到上下文对象，如何使用上下文对象将其提供给另一个捆绑包。

3. OSGI环境的所有注册对象是否都存储在一个地方，可以由使用上下文对象部署的任何捆绑软件检索到，或者我必须使用其他逻辑。
