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>
