非嵌入模式执行启动 SofaArkBootstrap报unreachable invocation.

Describe the question or bug

public class Main {
    public static void main(String[] args) throws Throwable {
        SofaArkBootstrap.launch(args);
        System.out.println("Main classloader: " + Main.class.getClassLoader());
    }
}

这样直接启动 ark container 报

抛异常的位置在：

此时 master biz 是 DirectoryBizArchive，也就是支持从IDE启动的。

Expected behavior

这种情况是否应该处理一下？要不在IDE里就无法启动了

Environment

• SOFAArk version: 2.2.11
• JVM version (e.g. java -version): 11
• OS version (e.g. uname -a):
• Maven version:
• IDE version:

如果方便处理的话，可以直接提个 PR 来解决下哈。另外我们建议使用嵌入的方式启动

其实没太理解嵌入与非嵌入的区别。 「嵌入模式」启动后又回到 appClassLoader，而「非嵌入模式」启动后还是bizClassLoader，除此之外还有其他区别么？

[lvjing2]

是的，秉持着尽可能少的侵入应用的运行模式，通过嵌入模式我们让基座启动后还是 appClassLoader。
