Adding additional jar for logging breaks with 16.1 #17250
Description
Describe the bug
We configured GELF in our log4j.xml. For that we need to load the gelf.jar.
With infinispan 16.0 we solved the problem by adding the lib to the /opt/infinispan/server/lib folder in an own image.
FROM quay.io/infinispan/server:16.0.5
ARG GELF_LIB_URL=https://repo1.maven.org/maven2/biz/paluch/logging/logstash-gelf/1.15.1/logstash-gelf-1.15.1.jar
ARG OCI_SOURCE
LABEL org.opencontainers.image.source=$OCI_SOURCE
ADD --chown=infinispan "$GELF_LIB_URL" /opt/infinispan/server/lib/
Is there a (new) recommend way how to tackle this?
Expected behavior
The gelf logger can be found.
Actual behavior
With 16.1 this breaks when starting the server

I have got a similar issue upgrading from 15.2.0 final to 16.1.3
The infinispan server image 16.1.3 /server/lib contains below jars to push logs to Elastic . This set up worked in 15.2.0 but fails in 16.1.3

The classloading mechanism was reorganized to make it possible to use AOT. It's likely an issue with visibility. I'll have a look soon
tristantarrant commentedon Apr 19, 2026
can you also attach your log4j2.xml please?
tristantarrant commentedon Apr 19, 2026
I think I understand: in the new server, libraries are installed from the server process after logging has been configured. I need to restructure the order in which this happens

I have attached the log4j2.xml and the loglayout.json. The logs get shipped to a logstash endpoint.
I dont see the log4j-layout-template jar in the image 16.1.3
infinspan-serverlog.log
. I downloaded the zip file for windows on version infinispan-server-16.2.0.Dev01 and kept the jars under server/lib , it works fine. Indeed log4j-web is not required, I will clean up
The same set up doesn't work in the image 16.1.3/16.2.0.Dev01 with same jars under server/lib
