native-image specific micrometer-mp-metrics test failure in io.quarkus.micrometer.runtime.registry.json.JsonExporter, java.lang.NumberFormatException
**Describe the bug**
Micrometer test fails to parse output when run with native-image. It works just fine in JVM mode.

**Expected behavior**
The test passes for JVM mode and native-image alike.

**Actual behavior**
### JVM mode :heavy_check_mark: 
```
./mvnw verify -f integration-tests/pom.xml --fail-at-end -pl 'micrometer-mp-metrics' -Dno-format
