I guess I'll need trusted.ci.jenkins.io (cf #532) for this release.

I believe so yes. I do not have access. Maybe @timja does?

I thought that the transition to JEP-229 was complete enough on this repository that a new release will be created once the pull request is merged.

The only case that I know for generating the release on trusted.ci.jenkins.io is if we require a signed jar file. Is a signed jar file required with this change?

I have permission to launch releases of remoting on trusted.ci.jenkins.io, if needed.

@MarkEWaite this is a case for a backport on a version predating signature removal and JEP-229 setup.

Thanks @Vlatombe . I had missed that the destination branch is a backport.

Once it is merged, I believe that I can launch the build of the backport.

[Vlatombe]

Unsure what is going on with the windows build though...

#540

I guess I'll need trusted.ci.jenkins.io (cf #532) for this release.

https://release.ci.jenkins.io ftr, requires VPN access and release team membership.

(I see Mark has volunteered to trigger it, make sure you release the backport and not the master branch)

@MarkEWaite stable-4.13.x is ready for release (4.13.1). Thank you!
