When restarting Jenkins all job configurations for "Post-build Actions" -> Quality Gates Sonarqube Plugin are missing.

Jenkins reports Unreadable Data in "Manage Old Data":

There seems to be issues initiating the SonarHttpRequester classes from the config.xml file after restart.

When re-configuring the "Post-build Actions" again the plugin works until a new restart of Jenkins

The config.xml file is extremly bloated with configuration of the SonarHttpRequester node

<sonarHttpRequester class="org.quality.gates.sonar.api61.SonarHttpRequester61">
<context>
<context class="org.apache.http.protocol.BasicHttpContext">
<map class="concurrent-hash-map"/>
</context>
</context>
<client class="org.apache.http.impl.client.InternalHttpClient">
... Another 35000 lines of configuration

Jenkins was started in cmd line using:

java -Dhudson.model.ParametersAction.keepUndefinedParameters=true -Xms512M -Xmx2048M -jar jenkins.war --controlPort=8001

One maven build job was created that executed a Sonar mvn job:

-U clean install $SONAR_MAVEN_GOAL -Dsonar.host.url=$SONAR_HOST_URL -Dsonar.branch=master

Prepare SonarQube Scanner environment was checked.

Quality Gates SonarQube Plugin config:
