Warnings about `@io.quarkus.arc.runtime.devconsole.Monitored` on private methods
### Describe the bug

I see several warnings about `@io.quarkus.arc.runtime.devconsole.Monitored` on private methods of Infinispan classes when using Quarkus main in dev mode. Noticed when looking into https://github.com/quarkusio/quarkus/pull/21267

I think these warnings should be eliminated, it's distraction when using dev mode.

### Expected behavior

No warnings related to `@io.quarkus.arc.runtime.devconsole.Monitored`

### Actual behavior

warnings present:

### How to Reproduce?

mvn io.quarkus.platform:quarkus-maven-plugin:999-SNAPSHOT:create -DprojectGroupId=my-groupId -DprojectArtifactId=my-app -DprojectVersion=1.0.0-SNAPSHOT -DpackageName=org.my.group -DplatformGroupId=io.quarkus -DplatformArtifactId=quarkus-bom -DplatformVersion=999-SNAPSHOT -DquarkusRegistryClient=false -Dextensions=quarkus-infinispan-client,quarkus-micrometer

mvn -f my-app quarkus:dev
