   最新版本会对这个异常做一些处理，参考： 
   1. https://github.com/apache/servicecomb-java-chassis/pull/1699/files ： 错误消息修改
   2. https://github.com/apache/servicecomb-java-chassis/pull/1687 业务抛出的所有异常都会经过 ExceptionToProducerResponseConverter 处理
   
   可以看下你的异常是哪里抛出来的，如果是业务抛出来的，参考 2 的示例，定制一个 ExceptionToProducerResponseConverter  即可。 如果是 handler 处理过程中抛出的， 可以写一个 ExceptionHanlder，放到所有 Hanlder 前面， 可以处理所有捕获到的异常。 实现 这个 handler 可以参考 https://docs.servicecomb.io/java-chassis/zh_CN/featured-topics/features/trace-id/ 这里的例子。
