For Java/Web/Cloud platforms, the trace manager now uses log4j 2 (version 2.17.1) instead of log4j 1.

As a result, the old log4j configuration files are no longer valid.

For Java/Web platforms, configured previously via a log4j.properties file, it will now have to be done by using a log4j2.xml file. An example file with the reference log4j2.xml.new is provided in the "javarun" subdirectory of the Adelia installation directory. Details of the syntax of the log4j 2 configuration files are available here.
