Error parsing log4j2.xml

[lolodomo]

At the very first startup of openHAB (from an offline distribution) snapshot 2631, I got this error:

13:44:23.308 [INFO ] [org.openhab.ui.internal.UIService    ] - Started UI on port 8080
[Fatal Error] log4j2.xml:1:1: Fin prématurée du fichier.
org.ops4j.pax.logging.pax-logging-api [log4j2] ERROR : Error parsing /home/pi/openhab/userdata/etc/log4j2.xml

Not occurring again after a restart.

This is still happening sometimes, I saw this error in recent snapshots

Based on the timestamps it looks like the log4j2.xml file is always modified on startup. So maybe it is sometimes written/read at the same time causing this issue?

Karaf always updates this logger on startup:

openhab-distro/distributions/openhab/src/main/resources/userdata/etc/log4j2.xml

Lines 124 to 126 in 79cc7ca

	<!-- Added by Karaf to prevent debug logging loops, see -->
	<!-- https://issues.apache.org/jira/browse/KARAF-5559 -->
	<Logger level="WARN" name="org.apache.sshd"/>

which probably causes the file to be modified.

I saw this error again few minutes ago when installing today snapshot (3209).

I got it again when starting snapshot 3360:

Just got it again when I started the snapshot 3434 for the first time.
