Step to reproduce:

• create a maven job
• check "Resolve artifacts from Artifactory" box and configure instance and repositories
• stop jenkins
• start jenkins

"Resolve artifacts from Artifactory" is not checked anymore and instance and repositories configuration is lost.

• go to administrativeMonitor/OldData/manage jenkins page and you will see the following message:
