java.net.http.HttpClient fails to timely recognize 204 response

    XMLWordPrintable

    Details

    • Subcomponent:
    • CPU:
      x86_64
    • OS:
      linux

      Description

      ADDITIONAL SYSTEM INFORMATION :
      Linux-x64, Alpine Linux, musl, openjdk-11 build 28

      A DESCRIPTION OF THE PROBLEM :
      java.net.http.HttpClient does not provide response (status 204) until 1 minute has passed. This appears to correlate with some sort of keep-alive or timeout configuration and not with response time from http server.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      The following steps requires that docker is installed:
      1. $ git clone https://github.com/kimcs/javanethttp204bug.git
      2. $ cd javanethttp204bug
      3. $ docker build -t javanethttp204bug .
      4. $ docker run -it javanethttp204bug

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Expected all http requests to respond within at most a few milliseconds, including the response with status-code 204.
      ACTUAL -
      A 1 minute wait-time to recognize the 204 response. Standard out produce a "TEST FAILED" line at the very end.

      CUSTOMER SUBMITTED WORKAROUND :
      Either of the following are workarounds:
      1. Not using musl linked JDK 11 for Alpine Linux distributions, rather use JDK 11 linked to normal glibc.
      2. Not using 204 response code in your http-server application. E.g. use 200 instead.
