-----------------------------------------
Summary: Property substitution not working if <Properties> tag is
not placed at the beginning of configuration
Key: LOG4J2-2500
URL: https://issues.apache.org/jira/browse/LOG4J2-2500
Project: Log4j 2
Issue Type: Bug
Components: Core
Affects Versions: 2.11.1
Environment: Any project with log4j using as configuration a file like
the one attached as example.
With this configuration, logs will be printed as ${defaultLayout} instead of
the actual message.
Reporter: Javier Armendáriz
Attachments: log4j2.xml
Tweaking my log configuration I found out that if the <Properties> is not
placed at the beginning of the config just after the <Configuration> tag, the
property substitution is not performed at all.
Looking at the documentation I haven't seen anything related to the ordering of
the elements in the config files. If there's a good reason that the properties
should be placed first place in configuration, it'd be a good idea to note it
somewhere in the documentation.
