evernat commented on JENKINS-9116:
----------------------------------
@pgweiss
it seems that you have committed that change so this issue is probably fixed:
https://github.com/jenkinsci/description-setter-plugin/commit/8c19a4d8a8775303d6a7c30cf07282b40fc34c5e
and it was released in the plugin v1.8
> Doesn't handle group matches that are null

> Key: JENKINS-9116

> Project: Jenkins
> Issue Type: Bug
> Components: description-setter
> Reporter: pgweiss

> If my regex is:
> ^URL: (\S)+( .*)?$
> And my replacement text is:
> <a href="\1">My URL\2</a>
> It is possible that the regex can succeed and the matcher.group(2) will be
> null. If that happens the description setter fails like this:
> ERROR: Publisher hudson.plugins.descriptionsetter.DescriptionSetterPublisher
> aborted due to exception
> java.lang.NullPointerException
> at java.lang.String.replace(String.java:2208)
> at
> hudson.plugins.descriptionsetter.DescriptionSetterPublisher.getExpandedDescription(DescriptionSetterPublisher.java:158)

> at hudson.model.Executor.run(Executor.java:145)
> This can probably be fixed by changing:
> result = result.replace("\\" + i, matcher.group(i))
> to
> result = result.replace("\\" + i, matcher.group(i) == null ? '' :
> matcher.group(i))
> But I haven't actually checked it.
