Updates through proxy server with authentication not working after update to core 2.152 or higher

    • Jenkins >= 2.152, Server-JRE 1.8.0_191 on Windows Server 2008R2
    • Jenkins 2.162

       After update to any Jenkins core higher (as of writing this ticket) than 2.151 I cannot check for updates any more from behind our company's proxy server. Error given by Jenkins Web Frontend is 

      There were errors checking the update sites: IOException: Server returned HTTP response code: 407 for URL: http://ftp-nyc.osuosl.org/pub/jenkins/updates/current/update-center.json

      So it seems that Jenkins is no longer authenticating to the proxy with the credentials configued in the plugin manager advandced tab.

      From the changelog I've seen that there were changes to the update code as part of issue 54459.

      So I've tried setting the referenced properties (even with all the spellings as indicated in the issue ticket):

       

      -Dhudson.PluginManager.checkUpdateSleepTimeMillis=2500 -Dhudson.PluginManager.CHECK_UPDATE_ATTEMPTS=5 -Dhudson.PluginManager.checkUpdateAttempts=5

      That has changed the duration until the above error appears. But it didn't fix the problem.

       

      The update center is configured as indicated in the attached screenshot.
      Strange thing is, that pressing the "Validate Proxy" button returns "Success" while the bottom of the same page shows the proxy auth required message (see screenshot). This seems to be very inconsistent.

      The Jenkins log contains the following (after setting above properties, same appears 5 times):

      Downgrading Jenkins core back to 2.151 immediately removes the issue. So this cannot be related in any way to a changed proxy server configuration.

      Setting this to Blocker as we're not able to install any more new plugins or plugin updates with Jenkins Core >= 2.152.
