微服务启动失败 -- NullPointer问题

首先阅读第 90 行的 CseApplicationListener.java，并按照堆栈跟踪中显示的启动路径进行跟踪，尤其关注记录的 CSE DOWN 状态附近。完成的标志是微服务启动路径不再因这个 NullPointerException 失败，并且通过验证覆盖了疑似的 null 状态。

2.6.0版本，微服务在启动的时候，偶现微服务启动失败，错误日志中显示是由空指针引起的
错误日志如下

单纯从代码中看，是在CSEApplicationListener中的 scbEngine.getProducerProviderManager().getProducerProviderList()可能出现了空指针，请问这块是否可以做一下加固？
