>                 URL: https://issues.apache.org/jira/browse/LOG4J2-1833
>             Project: Log4j 2
>          Issue Type: Bug
>    Affects Versions: 2.8.1
>         Environment: Windows 7 64-bit JDK 8
>            Reporter: Austin Huck
>            Priority: Minor
>
> When using a {{RollingFileAppender}} with a {{DirectWriteRolloverStrategy}} 
> if the _fileName_ property of the appender is set, rollover fails with a 
> {{NullPointerException}}. If the _fileName_ attribute is not present logging 
> works as intended.
