Yeah ... found out that too ... "Thread dumps" link in Jenkins job has 
shown the multiplle calls.
Wasn't aware of the property cabability.

Thank you

Jenkins Pipeline with custom class does hang forever

[thomas . lehmann]

Hi,

I were trying to write custom class in Jenkinsfile.

With following example the JOb does hang after the line "echo hi:2". I have 
to click to abort the build and then click twice
on provided links in the Jenkins Console to fully cancel it. On our server 
- even after kill - Jenkins remains 200 and more percentage of CPU.
We were forced to shutdown the Service and to restart. Locally I'm running 
Jenkins inside a Docker container. No CPU problems there.
I'm using a 2.8 and on our server we have a 2.23.

The Console output looks like this:

hi:2
Aborted by Thomas Lehmann 

Click here to forcibly terminate running steps 


Terminating node

Click here to forcibly kill entire build 


Hard kill!
Finished: ABORTED


And ideas?

Kind Regards,
Thomas

class Project implements Serializable {
static final serialVersionUID = 1L

private String message = ""

def setMessage(String message) {
this.message = message
}

def getMessage() {
return this.message
}
}

node {
echo "hi:1"
def project = new Project()

stage("Using a class") {
echo "hi:2"
project.setMessage("some message")
echo "hi:3"
echo project.getMessage()
echo "hi:4"
}
}
