Re: Attempt to (de-)serialize anonymous class org.jenkinsci.plugins.envinject.EnvInjectComputerListener$2

Although marked as duplicate of a fixed issue, this is still not fixed in enviniject 2.1.6, jenkins 2.148

Holger Sunke I have been trying to reproduce this error with envinject plugin 2.1.6 and Jenkins LTS 2.138.2, and have been unable to, but I do see reports of this warning from others.

Can you please provide the steps to reproduce this bug?

We also face the same problem in with Jenkins version 2.150.1 during connect with the agent.jar.

All I did was disconnect the slave and reconnect again.

The warning would always show up right before the line "Agent successfully connected and online".

I am experiencing the same issue with a recent upgrade using the following environment listed below.

Warning message on agent:

.....
Jan 14, 2019 11:36:15 AM hudson.remoting.jnlp.Main$CuiListener status
INFO: Connected
Jan 14, 2019 11:36:21 AM org.jenkinsci.remoting.util.AnonymousClassWarnings warn
WARNING: Attempt to (de-)serialize anonymous class org.jenkinsci.plugins.envinject.EnvInjectComputerListener$2; see: https://jenkins.io/redirect/serialization-of-anonymous-classes/

Environment:

EnvInject 2.1.6
EnvInject API 1.5

Agent: Windows 10 Build 1803 (fully patched)
Master: CentOS 6.10
Java: 1.8.0_191 (Master and Agents)

One piece of troubleshooting was replacing the agent.jar file with the previous slave.jar file and bringing the agent online successfully without the warning message.

Re: Attempt to (de-)serialize anonymous class org.jenkinsci.plugins.envinject.EnvInjectComputerListener$2

Timothy Donohue Can you please share your old slave.jar file with me? 

I do not have any backup and the fix by Josh Soref is still in unreleased state. 

Is there any other workaround, I can use for this issue meanwhile?

Re: Attempt to (de-)serialize anonymous class org.jenkinsci.plugins.envinject.EnvInjectComputerListener$2

How did you replace the agent.jar with the previous slave.jar?  (I'm here because I got that message, AND because my slave execution takes 20GIG of ram!:

 

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4539 engineer 20 0 20.738g 224564 14776 S 0.3 0.3 0:49.35 java

 

and am trying to see if I can do anything to make it better)

Also, what do I need to do to GET the 'fixed' version, since supposedly it is fixed (assuming that's why it was resolved!  I am using
h1. 2.176.2

of Jenkins)
