Upgrading to Jenkins LTS 2.176.x documentation has erroneous information

Issue Type:	Improvement
Assignee:	rsandell
Components:	core, gerrit-trigger-plugin
Created:	2019-08-30 12:35
Environment:	Jenkins LTS 2.176.x
Priority:	Minor
Reporter:	George Cimpoies

After upgrading to Jenkins LTS 2.176, the Server Status page in Gerrit Trigger section didn't display any information, showing a "Data error" message.

Logs:

 
                                                                2019-08-30 09:47:15.644+0000 [id=65732] WARNING j.s.s.StaplerFilteredActionListener#onGetterTrigger: New Stapler routing rules result in the URL "/gerrit-trigger/serverStatuses" no longer being allowed. If you consider it safe to use, add the following to the whitelist: "method com.sonyericsson.hudson.plugins.gerrit.trigger.GerritManagement getServerStatuses". Learn more: https://jenkins.io/redirect/stapler-routing 
                                                            

The line

 
                                                                method com.sonyericsson.hudson.plugins.gerrit.trigger.GerritManagement getServerStatuses 
                                                            

is wrong, because it doesn't work upon testing. Instead, the correct line to be added to the whitelist is

 
                                                                com.sonyericsson.hudson.plugins.gerrit.trigger.GerritManagement serverStatuses 
                                                            

as per

https://jenkins.io/doc/upgrade-guide/2.176/#upgrading-to-jenkins-lts-2-176-x

If one doesn't have enough Jenkins / debugging experience, an error like this can become very hard to track down and fix.
