Austin Huck updated LOG4J2-1833:
--------------------------------
Description:
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.
Configuration that produces this error:

<Configuration status="warn" name="MyApp" packages="">
<Properties>
<Property name="baseDir">C:/logs</Property>
