Re: Java 11 is the recommended version to run Jenkins on

[Mark Waite]

Good point.  More details on the transition to Java 11 are included in the 
2.303.1 
upgrade guide 
.
  
The upgrade guide includes a list of plugins known to be incompatible with 
Java 11.

?????? thread safety of scripted pipeline parallel and usage of nested parallel

['abstrakta' via Jenkins Users]

https://www.jenkins.io/doc/book/pipeline/scaling-pipeline/ says that durability 
is the ability of restarting running jobs even if Jenkins server restarts or 
system crashes.It seems not much useful. Jenkins server seems not so easy to 
crash.
What are some subtle bugs related to Pipeline durability with nested parallel 
steps in the past?I'd like to use need parallel if possible.In some situations, 
nested parallel is useful.
For example,you want build artifacts in A,B,C platforms parallelly.Then you run 
test artifacts in corresponding A(A1 A2 A3), B(B1 B2 B3), C(C1 C2 C3).If not 
using nested parallel, you must wait for A,B,C all finish their building to 
start test.If building A cost 10mins, building B cost 40mins, branch A don't 
need to wait the remaining 30min.Nested parallel can reduce this kind of 
waitting time,branch A just start its own parallel test after branch A finish, 
without waitting branch B.In the meantime, if branch A fails, branch B will 
continue to run B's test, which is originally not related to branch A's fail.
If you spilt nested parallel into two sequential parallel, you must handle the 
fails of different branch, only start test for successful build platforms.Or if 
you spilt nested parallel into two Jenkins build jobs,it seems splitting two 
related things, which make things harder to understand.

Thanks.

https://github.com/jenkinsci/workflow-cps-plugin#technical-design for a few 
more details. You should not need to worry about Java thread safety across the 
various branches in a parallel step as long as you are not doing anything with 
Java threads directly in your Pipeline.

Re: Resource Root Problem Post Upgrade

[Matt Wilson]

I managed to get a service restart last night.  I just reapplied my 
resource root url setting.
mystery continues at this point.  After reapplying my settings, I can 
download artifacts with no problem.  The logs are clean with respect to 
these downloads, nothing out of the ordinary.

when I reload my config page though I see an error below my resource url 
just as before (see attached).  The stack trace is the same as before.
I'm going to wait it out right now, but I'm expecting this will stop 
working at somepoint over the next day or so.  I have no idea if this 
"error" message was present before the upgrade to this version.

Somewhere it states that not all plug-ins support Java 11 also.

Jenkins continues to support Java 8.  We recommend Java 11.

See https://www.jenkins.io/blog/2021/08/17/docker-images-use-jdk-11-by-default/ 
for more details on the rationale for that transition.
