Anything else?

I'm not a Java developer, Claude offered this insight:

core/src/main/resources/lib/layout/details-bar.jelly at line 42 unconditionally sets an href attribute on an <x:element>, even when detail.link is null:

<x:element name="${detail.link != null ? 'a' : 'div'}">
    <x:attribute name="href">${detail.link}</x:attribute>   <!-- line 42: NPE -->

The element name is conditionally chosen (<a> when link exists, <div> when null), but the href attribute is always evaluated regardless — causing a NullPointerException when detail.link is null.

Why null links are valid

The Detail base class (jenkins.model.details.Detail) explicitly declares getLink() as @Nullable with a default return value of null:

public @Nullable String getLink() {
    return null;
}

When this was introduced

The details-bar.jelly template was introduced/modified by two PRs in September 2025 as part of the experimental run details UI:

• PR Refine experimental run details interface #11096 (Sep 25, 2025) — "Refine experimental run details interface"
• PR Fix description merge #11126 (Sep 29, 2025) — "Fix description merge" (restored a lost commit from Refine experimental add/edit description button #11103)

Are you interested in contributing a fix?

I'm not a Java developer. Claude offered the following solution:

File: core/src/main/resources/lib/layout/details-bar.jelly
Line: 42

Wrap the href attribute assignment in a null check:

<x:element name="${detail.link != null ? 'a' : 'div'}">
    <j:if test="${detail.link != null}">
        <x:attribute name="href">${detail.link}</x:attribute>
    </j:if>

hi, @darrenjones24
can you please assign this bug to me to work on it?

hi, @darrenjones24 can you please assign this bug to me to work on it?

I don't see that I have permission to assign bugs, it's all greyed out.

We don't generally assign issues to those who are not maintainers. It has not worked well in the past.

You're welcome to start working on this and open a pull request when you have a fix working locally.

I'm unable to duplicate the issue based on the provided description. Please provide enough details so that others can duplicate the issue from a fresh installation of Jenkins. Steps that I took include:

1. Download gh-26436.zip and unpack it
2. Change to the gh-26436 directory and run the command bash ./README
3. Allow Jenkins to finish initialization. It should have an agent defined and running and the plugins you listed
4. Run the a-pipeline job several times
5. Open the Pipeline overview and expand the logs on the sample job. No null pointer exception is reported

Hi Mark.

The error was triggered using the pipeline-graph-view plugin, and occurs when expanding the logs from graph view, but I believe the bug exists in the details-bar.jelly.

Thanks @darrenjones24, but those are the steps that I used when I attempted to duplicate it. We need more details to identify what is different about your environment compared to all the other environments. Please provide those details.

I took additional steps and still was unable to duplicate the issue. The additional steps that I took included:

1. Download gh-26436.zip and unpack it
2. Change to the gh-26436 directory and run the command bash ./README
3. Allow Jenkins to finish initialization. It has an agent defined and running and the plugins you listed
4. Run the a-pipeline job several times
5. Open the Pipeline overview and expand the logs on the sample job. No null pointer exception is reported
6. Edit the a-pipeline job to add more stages
7. Run the a-pipeline job several times
8. Open the Pipeline overview and expand the logs on the sample job. No null pointer exception is reported

The first Pipeline that I used was:

pipeline {
    agent any
    stages {
        stage('Hello') {
            steps {
                echo 'Hello World'
            }
        }
    }
}

The edited Pipeline was:

pipeline {
    agent any
    stages {
        stage('Hello') {
            steps {
                echo 'Hello World'
            }
        }
        stage('Brief') {
            steps {
                echo 'A midday greeting'
            }
        }
        stage('Salutation') {
            steps {
                echo 'Goodbye World'
            }
        }
    }
}

I've also tried to duplicate the issue on ci.jenkins.io with the git plugin job and the git plugin lastBuild job.

Please provide enough details so that others can duplicate the issue.

Thank You @MarkEWaite I do appreciate your thoroughness.
Although I have tried, I've not been able to reproduce this in a simple way for others to follow.

I can reproduce the issue in a clean build using our JCasC, but this is running multibranch pipelines on kubernetes using the github-branch-source-plugin (AFAIK) I've not been able to replicate that in the time available.

Thanks for making the attempt. My suspicion is that there is some global configuration that makes the issue visible. If you are willing to share a redacted form of your configuration as code definition, that may help others identify the steps to duplicate the issue.

As one theory, since you have both Blue Ocean and Pipeline Graph View installed, have you configured some portion of Jenkins to prefer Blue Ocean?

I tried various combinations of those configuration settings without duplicating the issue.
