com.alibaba.dubbo.rpc.protocol.hessian.HessianProtocolTest fails occasionally #1667
Description
@htynkn mentions in mailing list:
For now, I can only reproduce this issue in travis ci with jdk9 (refer to logs: https://api.travis-ci.org/v3/job/365133362/log.txt). I also did some test with my own machine:
Mac 10.13.2 with Jdk7, Jdk8 and Jdk9 can't reproduce this issue
Window 8 with jdk8 can reproduce this issue, I run test 1000 times, 247 of them are fail.
The only thing I can think about is hessian.overload.method config for hessian protocol. After I set this value to true in test. I can't reproduce this issue both in travis ci(refer to https://api.travis-ci.org/v3/job/365152345/log.txt) and my own machine.
