>             Project: Log4j 2
>          Issue Type: Bug
>          Components: JsonTemplateLayout
>    Affects Versions: 2.17.1
>         Environment: Tested on ServiceMix (under Docker) 7.0.1, but it should be the same in Karaf 4.x
> I also tried to add the original log4j2-api and log4j-core in the same config but the fragment never gets resolved.

> In the [pom|https://github.com/apache/logging-log4j2/blob/release-2.x/log4j-layout-template-json/pom.xml] of the module we have:
> {code:xml}
> <plugin>
>         <groupId>org.apache.felix</groupId>
>         <artifactId>maven-bundle-plugin</artifactId>
>         <configuration>
>           <instructions>
>             <Fragment-Host>org.apache.logging.log4j.layout.template.json</Fragment-Host>
>             <Export-Package>*</Export-Package>
>           </instructions>
>         </configuration>
>       </plugin>
> {code}
> The Fragment host seems to refer to itself.
> When I tried to deploy this jar as a bundle with this in my startup.properties file: 
> {noformat}
> mvn\:org.apache.logging.log4j/log4j-layout-template-json/2.17.1 = 5
> mvn\:org.ops4j.pax.logging/pax-logging-log4j2-extra/1.11.13 = 6
> mvn\:org.ops4j.pax.logging/pax-logging-api/1.11.13 = 8
> mvn\:org.ops4j.pax.logging/pax-logging-log4j2/1.11.13 = 8
> {noformat}
> And copying the lib in the "system" folder of karaf (I tried with ServiceMix 7.0.1).
> The bundle stays in status "Installed" and never resolves as the Fragment-Host refers to itself.
> I am not sure what values should be set in this as I am using Pax Logging, but for sure the Host does not seems correct to me (otherwise I would have created a PR).
