After downgrading SonarJava to 5.5.0.14655 it worked again.
This issue might be related to: [SONAR-11279] - Jira
Difference is that that one is reported against SonarQube itself and not the plugin.

Hi,

The issue can’t relate to the ticket you mentioned.

We dig a bit into SQ and sonar-java with the information you provided, we couldn’t find anything to explain the error.
It’s more likely the error comes from another plugin, triggered by the installation of a newer version of sonar-java.

At this point, I would advise you do the following experiments to narrow down the search:

  • check whether the error also comes when updating to a sonar-java between 5.5.0 and 5.8.0
  • check whether the error disappears when removing non SonarSource plugins one by one
  • same with removing sonarsource plugins one by one

Cheers

Hi,

Thanks for the fast reply. You said:

It’s more likely the error comes from another plugin, triggered by the installation of a newer version of sonar-java.

But why is it solved then, by only reverting sonar-java back to 5.5.0.
We did this by downloading the old version of the plugin and putting it to $SONARQUBE_HOME/extensions/plugins.

Regards

Hi,

That would be because the other plugin was relying on a behavior (exploiting a bug?) in SonarJava that changed in the new version.

Regardless, I would start by uninstalling the Timeline plugin, which is long-since deprecated & of no practical value since SonarQube v6.2, which dropped dashboards. Sonargraph Integration is the other possibly suspect (non-SonarSource) plugin I see in your list. (We don’t own l10n-de either, but the likelihood of that being involved in your problem is minute).
