Active connection to MongoDB required for fresh project based on master, wasn't needed for 1.7.0.Final and prior.
Getting NPE from SmallRyeMetricsRecorder.registerMetrics(SmallRyeMetricsRecorder.java:217)

Reproducer:

• build Quarkus master
• clone https://github.com/quarkus-qe/beefy-scenarios
• run mvn clean verify -pl 002-quarkus-all-extensions/

mvn clean verify -pl 002-quarkus-all-extensions/ -Dquarkus.platform.version=1.7.0.Final -Dquarkus-plugin.version=1.7.0.Final passes

@jmartisk fyi

This doesn't look related to MongoDB, I can reproduce this with Neo4j instead (and it makes sense, because we've only recently added Neo4j metrics support). Your test suite seems to be importing Neo4j, so I think that's the culprit. Otherwise the nature of the issue stays the same.

Thanks @jmartisk for looking at this, just wanted to comment, that Quarkus based on b35c0bf worked fine, so the changes affecting this had to be merged last Friday.

Yes, this was introduced via #11637
I've already submitted a PR to fix it: #11743
