The Apache Commons Net library implements the client side of many basic Internet protocols. The purpose of the library is to provide fundamental protocol access, not higher-level abstractions.

Kafka is a distributed streaming platform, which means:

• it can publish and subscribe to streams of records;

• it can store streams of records in a fault-tolerant way;

• it can process streams of records as they occur.

Eclipse LSP4J provides Java bindings for the Language Server Protocol and the Debug Adapter Protocol. This package contains its JSON-RPC implementation.

Although the java.net package provides basic functionality for accessing resources via HTTP, it doesn't provide the full flexibility or functionality needed by many applications. HttpClient seeks to fill this void by providing an efficient, up-to-date, and feature-rich package implementing the client side of the most recent HTTP standards and recommendations.

Logback is intended as a successor to the popular log4j project. This module can be assimilated to a significantly improved version of log4j. Moreover, logback-classic natively implements the slf4j API so that you can readily switch back and forth between logback and other logging frameworks such as log4j or java.util.logging (JUL).

This package implements POJO type materialization. Databinders can construct implementation classes for Java interfaces as part of deserialization.

The Logging package is a thin bridge between different logging implementations. A library that uses the commons-logging API can be used with any logging implementation at runtime.

This package provides the common Eclipse runtime.

Eclipse Parsson is an implementation of the Jakarta JSON Processing specification.

JMock is a library that supports test-driven development of Java code with mock objects. Mock objects help you design and test the interactions between the objects in your programs.

The jMock library

• makes it quick and easy to define mock objects

• lets you precisely specify the interactions between your objects, reducing the brittleness of your tests

• plugs into your favourite test framework

• is easy to extend.

Fest-test contains the common FEST testing infrastructure.

This package provides the Java development kit OpenJDK built with the IcedTea build harness.

Bnd is a swiss army knife for OSGi, it creates manifest headers based on analyzing the class code, it verifies the project settings, it manages project dependencies, gives diffs jars, and much more.

MVEL has largely been inspired by Java syntax, but has some fundamental differences aimed at making it more efficient as an expression language, such as operators that directly support collection, array and string matching, as well as regular expressions. MVEL is used to evaluate expressions written using Java syntax.

In addition to the expression language, MVEL serves as a templating language for configuration and string construction.

Ant is a platform-independent build tool for Java. It is similar to make but is implemented using the Java language, requires the Java platform, and is best suited to building Java projects. Ant uses XML to describe the build process and its dependencies, whereas Make uses Makefile format.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the support annotations for osgi-service-component.

Plexus-default-container is Plexus' inversion-of-control (IoC) container. It is composed of its public API and its default implementation.

SVG Salamander is an SVG engine for Java that's designed to be small, fast, and allow programmers to use it with a minimum of fuss. It's in particular targeted for making it easy to integrate SVG into Java games and making it much easier for artists to design 2D game content - from rich interactive menus to charts and graphcs to complex animations.

JMock is a library that supports test-driven development of Java code with mock objects. Mock objects help you design and test the interactions between the objects in your programs.

The jMock library

• makes it quick and easy to define mock objects

• lets you precisely specify the interactions between your objects, reducing the brittleness of your tests

• plugs into your favourite test framework

• is easy to extend.

This package provides support for the Eclipse extension registry.

OpenJFX is a client application platform for desktop, mobile and embedded systems built on Java. Its goal is to produce a modern, efficient, and fully featured toolkit for developing rich client applications. This package contains graphics-related classes for the OpenJFX distribution.

This package provides versions of the JavaMail API implementation, IMAP, SMTP, and POP3 service providers, some examples, and documentation for the JavaMail API.

The Jakarta-ORO Java classes are a set of text-processing Java classes that provide Perl5 compatible regular expressions, AWK-like regular expressions, glob expressions, and utility classes for performing substitutions, splits, filtering filenames, etc. This library is the successor of the OROMatcher, AwkTools, PerlTools, and TextTools libraries originally from ORO, Inc.

ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or dynamically generate classes, directly in binary form. The provided common transformations and analysis algorithms allow easily assembling custom complex transformations and code analysis tools.
