Bennett Lynch 47f82b6b20 Prefer Log4J2 over Log4J1 for default InternalLoggerFactory (#9734)
##Motivation

The InternalLoggerFactory attempts to instantiate different logger
implementations to discover what is available on the class path,
accepting the first implementation that does not throw an exception.

Currently, the default ordering will attempt to instantiate a Log4j1
logger before Log4j2. For environments where both Log4j1 and Log4j2 are
available, this will result in using the older version. It seems that it
would be more intuitive to prefer the newer version, when possible.

##Modifications

Change the default ordering to attempt to use the Log4J2LoggerFactory
before the Log4JLoggerFactory.

##Result

For environments where both Log4j1 and Log4j2 are available on the class
path (but Slf4J is not available), Netty will now use Log4j2 instead of
Log4j1.

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.

Usage with JDK 9

Netty can be used in modular JDK9 applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:

  • io.netty.all
  • io.netty.buffer
  • io.netty.codec
  • io.netty.codec.dns
  • io.netty.codec.haproxy
  • io.netty.codec.http
  • io.netty.codec.http2
  • io.netty.codec.memcache
  • io.netty.codec.mqtt
  • io.netty.codec.redis
  • io.netty.codec.smtp
  • io.netty.codec.socks
  • io.netty.codec.stomp
  • io.netty.codec.xml
  • io.netty.common
  • io.netty.handler
  • io.netty.handler.proxy
  • io.netty.resolver
  • io.netty.resolver.dns
  • io.netty.transport
  • io.netty.transport.epoll (native omitted - reserved keyword in Java)
  • io.netty.transport.kqueue (native omitted - reserved keyword in Java)
  • io.netty.transport.unix.common (native omitted - reserved keyword in Java)
  • io.netty.transport.rxtx
  • io.netty.transport.sctp
  • io.netty.transport.udt

Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately in your module-info file.
