Please review and provide feedback on https://cwiki.apache.org/confluence/display/LOGGING/Properties+Enhancement.
Note that some of the major goals of 3.0 are: * Fully support the Java Platform Module System by having all relevant jars contain a module-info.java class. * In support of JPMS, have log4j-core have as few dependencies as possible, including only requiring java.base. * The Log4jPlugins.dat file used in 2.x will not work well in a JPMS environment so ServiceLoader is now used to load plugin definitions. The Log4jPlugins.dat file will still be supported but compilation against the Log4j 3.0 annotation process will produce a Log4jPlugins.class instead as well as the required ServiceLoader file. * Move the Log4j annotation processor to its own Jar. It will not be invoked by default and will not be included at runtime. * Require Java 11 as the minimum, thus eliminating the need for multi-release jars. * If possible, improve the wiring of plugins by implementing a minimal dependency injection system. * Remove “strange” interfaces that had to be created before Java 8 provided default methods. While we will strive for as much backward compatibility as possible it is possible users may have to recompile their code or make minor changes. Thanks Ralph
