      Description

      This failure was observed once in jdk 9 b115 promotion testing. It looks to be rare and no evidence to be related with test environment. I re-ran with the same build and OS for 100 times but no fortune.

      Test output:
      ----------messages:(3/183)----------
      command: main -Djava.net.HttpClient.log=all QuickResponses
