I have 2 Webapps and an executable jar (3 in total) all using a very similar log4j2 set up.
All 3 apps look like the following
<configuration status="OFF" xmlns:xi="http://www.w3.org/2001/XInclude">
<Properties>
<Property name="logfile-name">LOGNAME.log</Property>
<Property name="logfile-folder">/home/${env:PUID}/utm/logs</Property>
<Property name="console-pattern">%d [%-6p] %C{1}.%M(%L) - %msg %n</Property>
<Property name="logfile-pattern">%d [%-6p] %C{1}.%M - %msg %n</Property>
<Property name="max-log-size">100 MB</Property>
<Property name="max-log-keep">12</Property>
<Property name="rolling-interval">1</Property>
</Properties>
<xi:include href="/opt/app/jtm/conf/jtm-log4j-appenders.xml" />
<xi:include href="/opt/app/jtm/conf/jtm-log4j-loggers.xml" />
</configuration>
Properties are passed into the appenders.xml and loggers.xml for all projects. It works fine for the Webapps.
The executable jarfile reports this error
[Warning] log4j2.xml:23:66: Include operation failed, reverting to fallback. Resource error reading file as XML (href='/opt/app/jtm/conf/jtm-log4j-appenders.xml'). Reason: no !/ in spec

I've looked in a few places on the web and there is nothing outright to answer this. I do get the feeling that it might be due to the executable jar reading from the file system but I'm struggling a little.
