Java agent 1.7.0 fails with prometheus exporter (regression)

[harel-e]

I tried to instrument an application with the latest 1.7.0 agent.

I used the following VM params (omitted full cmd for clarify)

-javaagent:opentelemetry-javaagent.jar
-Dotel.metrics.exporter=prometheus
-Dotel.exporter.prometheus.port=9464

I got the exception beflow.
It is working fine with agent version 1.6.2

Environment

JDK : OpenJDK 64-Bit Server VM Temurin-11.0.12+7
OS: MacOS 11.6

I'm going to move this issue over to the instrumentation repo, since it applies to the agent.

[mateuszrzeszutek]

Looks like the SDK uses prometheus 0.12.0, while the agent still has 0.11.0

We should patch this in 1.7.1 - and add a smoke test :)

Thank you. I also verified the fix.
