What is the business impact?
Jenkins stop working due the deadlock between support-core plugin and core/org.jenkinsci.plugins.workflow.support.steps.ExecutorStepExecution$PlaceholderTask$PlaceholderExecutable$1.interrupt(ExecutorStepExecution.java:570)
What is the incorrect behaviour?
The deadlock should not happen
What is the expected behaviour?
You should be able to automatically create a bundle and stop a build execution
Step by step to reproduce
N/A
Workaround
Restart the instance, disable support-core plugin or avoid to stop builds. Issue does not seems to be very frequent.
Regression
I don't think this is a regression.
Environment
support-core:2.32:not-pinned
Version: `2.7.21.1 (CloudBees Jenkins Enterprise 2.7.21.1-rolling)`
