Sorry for the blocker, but we will soon decide whether log4j2 will be dead for the next few years or not.

> Hi all Log4j/OSGi experts!
> Yesterday I started to migrate from log4j to log4j2. I replaced all Log4j 1.x bundles with log4j-1.2-api as described here: http://logging.apache.org/log4j/2.x/log4j-1.2-api/index.html
> But I got following error:
> Unresolved constraint in bundle MyBundle [21]: Unable to resolve 21.0: missing requirement [21.0] osgi.wiring.package; (&(osgi.wiring.package=org.apache.log4j)(version>=1.2.0)(!(version>=2.0.0)))
> so...I checked the capabilities of the log4j-1.2-api bundle:
> g! inspect cap * 11
> org.apache.logging.log4j-1.2-api [11] provides:
> -----------------------------------------------
> osgi.wiring.bundle; org.apache.logging.log4j-1.2-api 2.0.0.beta8 [UNUSED]
> osgi.wiring.host; org.apache.logging.log4j-1.2-api 2.0.0.beta8 [UNUSED]
> As you can see logging.log4j-1.2-api doesn't export the log4j API 1.2. It still requires log4j 1.2. All dependent bundles can not be resolved until I add the old log4j.jar.
> The maven-bundle-plugin does not export the packages.
