# Motivation: `DefaultByteBufHolder.equals()` considers another object equal if it's an instance of `ByteBufferHolder` and if the contents of two objects are equal. However, the behavior of `equals` method is not a part of the `ByteBufHolder` contract so `DefaultByteBufHolder`'s version may be causing violation of the symmetric property if other classes have different logic. There are already a few classes that are affected by this: `DefaultHttp2GoAwayFrame`, `DefaultHttp2UnknownFrame`, and `SctpMessage` are all overriding `equals` method breaking the symmetric property. Another effect of this behavior is that all instances with empty data are considered equal. That may not be desireable in the situations when instances are created for predefined constants, e.g. `FullBulkStringRedisMessage.NULL_INSTANCE` and `FullBulkStringRedisMessage.EMPTY_INSTANCE` in `codec-redis`. # Modification: Make `DefaultByteBufHolder.equals()` implementation only work for the objects of the same class. # Result: - The symmetric property of the `equals` method is restored for the classes in question. - Instances of different classes are not considered equal even if the content of the data they hold are the same. |

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:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
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

io.netty.transport.sctp

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