> if you look at the manifest in this jar:
> [https://repo1.maven.org/maven2/org/apache/logging/log4j/log4j-jcl/2.17.2/log4j-jcl-2.17.2.jar]

> then slf4j has the right OSGI manifest entries to work correctly with the ServiceLoader
> SLF4j has:

> Require-Capability: osgi.extender;filter:="(osgi.extender=osgi.service
> loader.registrar)",osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"
> Provide-Capability: osgi.serviceloader;osgi.serviceloader="org.slf4j.s

>
> JCL has:
>
> Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"
>
> this should become to fully support it in an OSGi environment:
>
> Require-Capability: osgi.extender;filter:="(osgi.extender=osgi.servicelo
> ader.registrar)",osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"
