Description

I use the JUL Adapter and when j.u.l.Loggers are loaded, I get the following exception

The failing code tries to resolve the @PluginFactory annotated method, which is missing for the ConsoleAppender class.

FileAppender's method is annotated and it works as expected. So I use this as workaround.
