DavideRossi opened a new issue, #2660:
URL: https://github.com/apache/jena/issues/2660
### Version
5.1.0
### What happened?
I have a Helidon MP-based app that uses an embedded Fuseki instance.
My `pom.xml` contains:
```
<dependency>
<groupId>org.apache.jena</groupId>
<artifactId>apache-jena-libs</artifactId>
<type>pom</type>
<version>${jena.version}</version>
<dependency>
<dependency>
<groupId>org.apache.jena</groupId>
<artifactId>jena-fuseki-main</artifactId>
<version>${jena.version}</version>
<dependency>
```
where `jena.version` is `5.1.0`.
As soon as my code executes `DatasetFactory.createTxnMem()` it crashes with
a `java.lang.NoClassDefFoundError:
io/micrometer/prometheusmetrics/PrometheusMeterRegistry` exception.
The code works just fine with previous Jena/Fuseki versions.
Maybe a missing Prometheus dependency?
### Relevant output and stacktrace
