微服务采用highway协议，只有highway-transport，日志一直有异常，java-chassis2.1

2020-11-12 10:29:07,247:ERROR vert.x-eventloop-thread-13 (TcpServer.java:82) - Unexpected error in server.cause:ClosedChannelException,message:null
改了空闲超时之类的没用。

Start by reproducing the highway-transport setup described for java-chassis 2.1 and inspect TcpServer.java at line 82, where the ClosedChannelException is logged. Trace the server.cause handling around that entry point and determine when the exception occurs. Done means the reported abnormal log is either prevented or correctly handled, with a regression test if the relevant test location is found.
