Ha, I feel dumb.  I clicked on the fix version link above rather than going to the main site.

> Hello,
> since two days I'm working with Log4j 2 . I try to migrate from Log4J. I'm using it in
an Eclipse application. I put the necessary jars of the binary distribution into a basic plugin
and a log4j2.xml into the root. This worked well so far. Now I tried to add a custom appender
to log4j. The class is in the default source package of the Eclipse plugin. Annotations are
set like in the homepage documentation.
> In the first try I tried to provide the package of the Appender via the log4j2.xml. I
set the attribute package in the configuration element. It seemed to me, the attribute is
completely ignored? At least the class from the given package was not loaded.
> In the second try I tried to provide the package via the static method '...log4j.core.config.plugin.PluginManager.addPackage'.
I debugged the method to get a hint why it didn't work. It tried to transform my package 'com.application.logging'
into a URI 'com/application/logging' and started to search with it somehow. It might have
found them treating them as file, as the classes were lying in a subdirectory. But as there
was no file scheme in the beginning of the URI, it searched a not existing jar.
> The XML parser of the configuration can't resolve the name of my appender in the end.
> Do you have an idea then I do anything wrong, or then there is an open issue? I can provide
more details on request. Is there a programmatical way to register my appender to Log4J 2
before the Logger initialization?
> Sincerely
> Robert Breunung
