Describe the bug
We use Apache Artemis with the artemis-prometheus-metrics-plugin. We want to use the java agent for collecting logging. After adding the java agent the metrics are not collected anymore and the /metrics endpoint could not be found anymore.
Steps to reproduce
Configure Artemis to use the prometheus plugin
Add the java agent to the startup command with following configuration.
JAVA_ARGS="$JAVA_ARGS -javaagent:/data/opentelemetry/opentelemetry-javaagent.jar"
JAVA_ARGS="$JAVA_ARGS -Dotel.logs.exporter=otlp"
JAVA_ARGS="$JAVA_ARGS -Dotel.metrics.exporter=none"
JAVA_ARGS="$JAVA_ARGS -Dotel.traces.exporter=none"
JAVA_ARGS="$JAVA_ARGS -Dotel.service.name=artemis-broker"
What did you expect to see?
The plugin keeps working and the logs are scraped.
What did you see instead?
The logs are scraped, but the /metrics endpoints is not available anymore. In the log I see the stacktrace below.
What version are you using?
Java agent 1.25.1
Environment
OS: Ubuntu 20.04.6 LTS
Runtime (if different from JDK above): OpenJdk Corretto-17.0.6.10.1
