Kotlin=报错｜拦截异常没有拦截住｜Throwable 和 Exception

示例代码中，抛出了个自定义异常
throw BOOMException(tokenBean.msg ?: BOOM_EXCEPTION_DEFAULT) // BOOM_EXCEPTION_DEFAULT 是常量，代表默认的异常信息。

但是报错了，try catch 没有拦截住。

因为 BOOMException 继承了 Throwable。
改为 继承 Exception ，可以正常拦截了。

原因：Exception 是 Throwable 的子类，catch 中拦截的是 Exception 不是 Throwable。

示例代码：

/**
     * 激活流程
     */
    fun token() {
        GlobalScope.launch(Dispatchers.Main) {
            try {

                val url = RetrofitManager.getApiService().urls()
                if (url?.code == 200) {
                    RoomConstants.saveUrl(url.data)
                    //同步服务器时间
                    url.data?.ts?.let {

                            it

                    val busSdkConfig = BoomMeeting.getBusSdkConfig()
                    val urls = url.data
