The logging engine has been changed from JUL to Log4j2 leveraging their asynchronous logger implementation by default.
The log4j2.xml configuration file has been placed into a new etc/ directory. The location can be changed by setting a property in the JAVA_OPTS environment variable:
export JAVA_OPTS="$JAVA_OPTS '-Dlog4j2.configurationFile=<another log4j2.xml location>'"
