> Components: Appenders
> Reporter: Christoph Kaser

> Time Spent: 40m

> When I try to use the RollingFileAppender with a DirectWriteRolloverStrategy
> and a HtmlLayout, I encountered a bug: The first file that is written does
> not start with the header from the layout.
> If I try to specify append=false to work around that issue, I encountered a
> NullPointerException instead:
> {noformat}
> java.lang.NullPointerException
