Description
servicecomb从2.7.8升级到2.8.18后，出现少量空指针异常，对实际业务没有什么影响，但是由于是新版本引入的，需要分析下原因。堆栈如下：
从堆栈可以看出抛出空指针的原因是由于RoutingContextImpl的fail方法获取的throwable对象为null
throwable来源于Http1xServerRequest的onData方法，按理来说这里e不应该为null

Research direction
Start with the stack traces and the named RoutingContextImpl.fail and Http1xServerRequest.onData methods, then compare their behavior between versions 2.7.8 and 2.8.18. Done means identifying how a null throwable reaches fail and documenting or fixing the regression with a reproducing test.
