Étienne Hossack created ARTEMIS-3278:
----------------------------------------
Summary: Artemis (classloader) is unable to find jgroups
configuration file
Key: ARTEMIS-3278
URL: https://issues.apache.org/jira/browse/ARTEMIS-3278
Project: ActiveMQ Artemis
Issue Type: Bug
Components: Broker, Configuration
Affects Versions: 2.17.0
Reporter: Étienne Hossack
Attachments: jgroups-file-ping.xml
The artemis broker is unable to use the jgroups configuration as per
documented. This issue is present both running on a system directly, or with
docker. Will explain docker approach. I have tested this on my machine, and a
teammates machine.
Steps to Reproduce (high level, detailed below):
# In artemis-docker directory, build dockerfile
# Add jgroups config to container
# modify broker xml to reference container
# restart broker (config is not reloaded)
# *broker crashes*
An exception is thrown by the config loader:
[https://github.com/apache/activemq-artemis/blob/e364961c8f035613f3ce4e3bdb3430a17efb0ffd/artemis-core-client/src/main/java/org/apache/activemq/artemis/api/core/JGroupsFileBroadcastEndpoint.java#L42]
despite the classpath supposedly having been altered:
[https://github.com/apache/activemq-artemis/blob/main/artemis-boot/src/main/java/org/apache/activemq/artemis/boot/Artemis.java#L82]
I have tried this by manually adding the classpath folder just in case:
-Xbootclasspath/a:$ARTEMIS_INSTANCE_ETC
{code:java}
./prepare-docker.sh --from-release --artemis-version 2.17.0
cd _TMP_/artemis/2.17.0
docker build -f ./docker/Dockerfile-adoptopenjdk-11 -t artemis-adoptopenjdk-11 .
docker run --name artemis -d -P -e EXTRA_ARGS="--clustered"
artemis-adoptopenjdk-11:latest
docker cp jgroups-file-ping.xml artemis:/var/lib/artemis-instance/etc/
docker exec -u root -it artemis bash
# in container edit using your editor of choice
mkdir /etc/jgroups && chmod -R 777 /etc/jgroups
apt-get update && apt-get install -y vim
vim etc/broker.xml
# modify and replace xml elements:

</cluster-connection>
</cluster-connections>
# exit. force reload
docker stop artemis
docker restart artemis && docker attach artemis
{code}
*Expected:* Broker then starts with jgroups discovery enabled using the
aforementioned filepine directory or complains about invalid configuration
*Actual:* Broker fails to start:
