Using Vert.x Auth, Native image build failures on GraalVM 21.1 with Random/SplittableRandom initialized at build time
## Describe the bug
Using the following Vert.x auth dependency:

```
<dependency>
    <groupId>io.vertx</groupId>
    <artifactId>vertx-auth-jwt</artifactId>
</dependency>
```

I'm aware that other community dependencies might not be working on Native, but unless we should provide workarounds for users to issues like this.

And then using the `io.vertx.ext.auth.jwt.JWTAuth`, for example:

```
@ApplicationScoped
public class JWTHandler {

    @Inject
    JWTAuth jwt;

    public void createJwt(final RoutingContext context) {
        String name = context.request().getParam("name");
        context.response()
                .putHeader("Content-Type", "application/json")
                .end(new JsonObject().put("jwt", jwt.generateToken(defaultClaims(name, "admin"))).encode());
    }
}
```

This fails to build on Native because JWTAuth uses `io.vertx.ext.auth.impl.jose.JWT` which contains a Random static field:

Error: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: Detected an instance of Random/SplittableRandom class in the image heap. Instances created during image generation have cached seed values and don't behave as expected.  To see how this object got instantiated use --trace-object-instantiation=java.util.Random. The object was probably created by a class initializer and is reachable from a static field. You can request class initialization at image runtime by using the option --initialize-at-run-time=<class-name>. Or you can write your own initialization methods and call them explicitly from your main entry point.

```

This is when using GraalVM 21.1, but it worked fine using GraalVM 21.0.

## To Reproduce

Steps to reproduce the behavior:
1. `git clone https://github.com/Sgitario/beefy-scenarios`
2. cd beefy-scenarios
3. git checkout reproducer_17653
4. cd 302-quarkus-vertx-jwt
4. mvn clean verify -Dnative -Dquarkus.native.container-build=true -Dquarkus.native.builder-image=quay.io/quarkus/ubi-quarkus-native-image:21.1-java11

## Environment (please complete the following information):
### GraalVM version (if different from Java)
21.1
### Quarkus version or git rev
999-SNAPSHOT (2.x)
