Environment

• CloudBees CI (CloudBees Core) on modern cloud platforms - Managed Master > 2.164.1.2
• CloudBees CI (CloudBees Core) on traditional platforms - Client Master > 2.164.1.2
• CloudBees Jenkins Enterprise - Managed Master > 2.164.1.2
• CloudBees Jenkins Platform - Client Master > 2.164.1.2
• CloudBees Jenkins Distribution > 2.164.1.2
• Jenkins LTS > 2.164.1
• Pipeline: Groovy (workflow-cps) plugin < 2.69

Resolution

This is a bug that was reported here: [JENKINS-56890] IOException: “cannot find current thread” - Jenkins JIRA
It affects environments with Jenkins versions above 2.164 and Pipeline: Groovy (workflow-cps) plugin below version 2.69

The solution is to upgrade the Pipeline: Groovy (workflow-cps) plugin to version 2.69 or higher

If you are a CloudBees customer, you may need to temporarily disable the CloudBees Assurance Program (CAP) in order to find the update as explained here: Plugins missing from Update Center after installing CloudBees Jenkins v2.x – CloudBees Support
If you would like to stay CAP compliant, please upgrade your CloudBees Jenkins instance to version 2.176.2.3 or higher as the updated plugin is included in these versions of CAP.
