      Kohsuke's updated summary

      In 1.485, there's a bug that causes Jenkins to return null when someone is listing historical build records. The caller is not expecting null return value, so this normally results in NullPointerException.

      Because there are numerous code inside Jenkins that touches build history, such NullPointerException can occur in a large number of different places.

      If you are not sure your NullPointerException is just another manifestation of this bug or an unrelated bug, please feel free to file a separate ticket, and mention this ticket as a possible cause so that the plugin developers won't get confused.

      Original bug report

      running the build fails with the following error:

      ERROR: Processing failed due to a bug in the code. Please report this to jenkinsci-users@googlegroups.com

          [JENKINS-15465] RunList returning null from its elements in 1.485

          We're facing the same issue after upgrading to 1.485. Seems like all our builds now fail with this error.

          JENKINS-15465 tweaking subList implementation and iterator.

          I can't really think of how null ends up in the resulting list, but adding a check in Iterator to detect that situation.

          Also, improved the efficiency of the subList implementation.

          Excellent - thanks! I just finished compiling Jenkins, in an attempt to fix it myself.

          Will there be a release soon, considering that this is a showstopper for many, or should people needing it right away compile their own version? Since this is an bundled plugin, updating jenkins.war should be enough I guess?

          (The RC-link http://mirrors.jenkins-ci.org/war-rc/latest/jenkins.war currently shows 404)

          Those who are seeing this issue, can you please try build #1987 or later and report what happens?

          This is a very critical bug that I'd like to fix quickly, so I really appreciate everyone's help.

          This issue only seems to crop up on about 1 in 3 startups of jenkins.

          It looks like the size of the array is shrinking from 22 to 21 during loading.

          Confirmed that I am seeing NPE's being thrown on M2 jobs with up/downstream dependencies. Standalone jobs with Maven build steps do not have this issue.

          I'm not seeing any data loss in any of my M2 jobs.

          It looks to me like the additional builds in the list are due to maven submodule builds where the top level build record no longer exists. I added debug into the removal codepath where it detects a null r value and the ones it is removing correspond to build records that only exist at the lower level

          The fix that I proposed for JENKINS-15439 does not fully fix the issue. It fixes the issue with AbstractLazyLoadRunMap search failing but I still see some null values in RunList.

          The null values are not present when Jenkins starts up but after a while (an hour or two) then the null values are present.

          In my case I have worked out that I can cause a symptom of the error to occur by reading the rssAll feed. Immediately after jenkins starts up this reads normally but when things have gone wrong the feed returns the error.

          A simple

           wget -O /tmp/rssAll.xml http://localhost:8080/jenkins/rssAll
          

          Will force the error.

          Stacktrace as follows.

          Caused by: javax.servlet.ServletException: org.apache.commons.jelly.JellyTagException: jar:file:/var/cache/jenkins/war/WEB-INF/lib/jenkins-core-1.487-SNAPSHOT.jar!/hudson/atom.jelly:48:44: <j:forEach> java.lang.NullPointerException

All of these are maven submodule entries. At this moment I am not sure if it is every submodule entry (with a build record) that is null but that is certainly a close approximation.

          @kohsuke I've got a pretty good handle on what is going on here but don't know enough about how maven multi-module projects fit together to get to the bottom of the issue.

          I can re-create the issue by simulating a low memory situation which forces soft-references to get cleared (i.e. cause an OOM) and then after that requesting the rssAll URL will cause the problem. This does require that the jenkins instance has some multi-module maven builds.

          http://localhost:8080/jenkins/rssAll
          

          Note that the single module builds all seem to be fine and have build history (indeed the top level build history of the multi-module looks fine). I suspect that something in the multi-module history is not getting rebuilt properly.

          Adding the following to a suitable view will allow you to force an OOM.

              public void doClearSoftReferences( StaplerRequest req, StaplerResponse rsp ) throws IOException, ServletException {
                  rsp.setContentType("text/plain");

          I found two issues when I upgraded Jenkins from 81 to 85.

          a. I could see all of my Ant based jobs. But missing to see Maven based builds (I found that I've upgraded the maven plugin from 1.478 to 1.485 which is causing the problem)

          b. Missing build history for some jobs (I think this is the issue with 1.485 Jenkins version)

          So I've downgraded Jenkins maven plug-in to see my previous Maven based builds. Now I've updated my 1.481 Jenkins to 1.484 and works fine as expected.

          @kohsuke the BuildReferenceMapAdapter does silently paper over the cracks and stops the /rssAll URL from falling over NPEs but all of the build records are gone after forcing an OOM. The size of the RSS drops from 256229 to 700 bytes.

          There is no suggestion that anything is wrong in the logs so that could potentially mask other real problems in the future. I can't think of any easy way round it to get the right balance between safety and diagnosablity

I can't really think of how null ends up in the resulting list, but adding a check in Iterator to detect that situation. Also, improved the efficiency of the subList implementation.

          @Tamas Papp. Your stack trace does not correspond with the symptoms reported against this issue. JENKINS-15499 is the same as yours and contrary to what I initially believed it seems that it is not related to the issue fixed in JENKINS-15465.

          I'm going to re-mark this issue as resolved and suggest that you follow JENKINS-15499 instead.
