Sure it'll need something like: I had that initially but then I removed it as I wasn't able to trigger any of these issues. Feel like contributing a fix? |

Hey @timja, thanks for reaching back, you mean to try adding those flags to this entry point https://github.com/jenkinsci/docker-inbound-agent/blob/master/jenkins-agent and test the agent again if works create a PR adding those flags for jdk17 entry point? ( https://github.com/jenkinsci/docker-inbound-agent/blob/master/jenkins-agent) |
|
Yes, bearing in mind that the entrypoint here uses |
|
Thanks @timja Connection Command Error log |
|
According to the error you need to add java.lang.reflect to the modules list |
|
Hey @timja I have added the following OPTS I still got an error @timja you mentioned you had this initially but then removed later, did you manage to fix error without these |
|
Next error is java.text initially I copied the options from jenkinsci/docker but then I tested without and found that basic steps worked fine without it |
|
Ya just added the following, running some tests |
|
What made you add java.awt.font? |
|
just removed the java.awt.font, not including in my tests, added it as I copy the --add-opens from the existing app. |
|
yes it requires --add-opens java.desktop/java.awt.font=ALL-UNNAMED |
|
You got a bigger stacktrace for it? |
|
Hey @timja sorry for late reply, below I have shared the error log |
|
Interesting, we can likely work around that in Jenkins core by removing that converter which we don't need, but it can be added to the |
|
True So moving forward @timja for users to use jdk17 should I add a PR for https://github.com/jenkinsci/docker-inbound-agent/blob/master/jenkins-agent or will it be added in Jenkins core with the next version? |
|
Add a PR for here for now please |
|
@timja sure, here do you suggest to add it for jdk17 docker image or create a new entry point file? |
|
same way as in jenkinsci/docker entrypoint, set an environment variable in the dockerfile https://github.com/jenkinsci/docker/blob/master/17/debian/bullseye/hotspot/Dockerfile#L105 then https://github.com/jenkinsci/docker/blob/master/jenkins.sh#L38 (remembering that script is bash, while this is using |
|
Does anyone have steps to reproduce this issue from scratch? I was thinking about moving the |
|
I tried to reproduce this and wasn't able to. =/ @bob-rohan do you have an example you could share from here? jenkinsci/docker-inbound-agent#252 |
|
I don't @timja , I not longer have access for the client where this work was done. I'll reach out see if someone could pick this up |
|
So maybe we should conclude that these |
|
we could remove for now and see if someone can provide a way to reproduce if we hit it. |
|
One YOLO PR coming up. |

@shawngmc That stack trace seems to come from the controller, so I have no idea why you are posting it on an issue in the |
Argh - you're right. That is from the controller. I think I simply copied/pasted into the wrong GitHub tab; pretty sure I meant to paste into jenkinsci/docker-plugin#905 Getting Jenkins itself, the docker plugin, and a docker jenkins worker image all talking together happily is... painful. |
|
Ping on this issue: is it still reproduceable or shall we close it? |
|
This ticket was filed in the wrong repository and was fixed in jenkinsci/jenkins#7270. |
