To reproduce, in log4j2.xml, specify a filePattern without a parent directory:
<appenders>
<RollingFile name="RollingFile" fileName="logs/app.log"
filePattern="fileWithoutParentDir-%d{MM-dd-yyyy}-%i.log.gz">
This can be fixed
in
org.apache.logging.log4j.core.appender.rolling.helper.FileRenameAction#execute(File,
File, boolean) (line 85)
by changing (CURRENT) if (!parent.exists()) {
to (FIX) if (parent != null && !parent.exists()) {
