----------------------------------------------------------------
Logger configuration is one that can accept null for the level. This is useful
when adding an appender ref to a logger but inheriting the level from {root}.
I have a patch ready for this but I'm waiting for the company CLA to be
forwarded to Apache so I can't submit a PR yet.

> Project: Log4j 2
> Issue Type: Bug
> Components: Configurators
> Affects Versions: 2.8.2
> Reporter: Paul Burrowes
> Assignee: Mikael Ståldal
>
> The default java {{XMLStreamWriterImpl}} {{writeXMLContent()}} requires that
> the content argument be non-null. Attributes in a Log4J component
> configuration may be null which breaks export.
> {{DefaultConfigurationBuilder.writeXmlAttributes()}} needs to perform a null
> check for every attribute before passing it to
> {{XMLStreamWriterImpl.writeAttribute()}}.
