> h2. Status Quo
> The "log4j core" and "log4j 1.2 api" library (and others as well) are build as bundle.
> The compatibility library is build as fragment.
> h2. Problem
> Using the log4j core and 1.2 api library in Eclipse-runtime (via [target platform|https://wiki.eclipse.org/PDE/Target_Definitions]) does not properly work out, since the _1.2 api_ fragment bundle is extending the _core_ bundle's api, by declaring extra _Export-Packages_ statements for log4j 1.2 api.
> Unfortunately Eclipse is not capable of resolving those extra added API (via {_}Export-Packages{_}) from a fragement, even though at runtime it is supposed to work.
> h2. Solution Proposal
> Add the following bundle manifest header to _core_ bundle, to support the extra added API by the _1.2 api_ fragement bundle:
> {code:java}
> Eclipse-ExtensibleAPI: true{code}
> Please see _The Eclipse-ExtensibleAPI Header_ section of Eclipse's [Platform Plugin-In Developer Guide|https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fbundle_manifest.html] documentation.
