Stax2 API is an extension to basic Stax 1.0 API that adds significant new functionalities, such as full-featured bi-direction validation interface and high-performance Typed Access API.

This package provides a library of matcher objects (also known as constraints or predicates) allowing match rules to be defined declaratively, to be used in other frameworks. Typical scenarios include testing frameworks, mocking libraries and UI validation rules.

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

This package provides an API for caching accessed HTTP resources.

Binding/provider for NOP, an implementation that silently discards all logging messages.

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 base classes for the OpenJFX distribution.

This package provides the Java development kit OpenJDK.

Guice is a lightweight dependency injection framework for Java 6 and above.

Dataformat backends are used to support format alternatives to JSON, supported by default. This is done by sub-classing Jackson core abstractions.

QDox is a high speed, small footprint parser for extracting class/interface/method definitions from source files complete with JavaDoc @tags. It is designed to be used by active code generators or documentation tools.

PowerMock is a framework that extends other mock libraries such as EasyMock with more powerful capabilities. PowerMock uses a custom classloader and bytecode manipulation to enable mocking of static methods, constructors, final classes and methods, private methods, removal of static initializers and more. By using a custom classloader no changes need to be done to the IDE or continuous integration servers which simplifies adoption.

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.

TreeLayout creates tree layouts for arbitrary trees. It is not restricted to a specific output or format, but can be used for any kind of two dimensional diagram. Examples are Swing based components, SVG files, etc. This is possible because TreeLayout separates the layout of a tree from the actual rendering.

The AOP Alliance project is a joint project between several software engineering people who are interested in Aspect-Oriented Programming (AOP) and Java.

Jansi is a Java library that allows you to use ANSI escape sequences to format your console output which works on every platform.

The modello test package contains the basis to create Modello generator unit-tests, including sample models and xml files to test every feature for every plugin.

StringTemplate is a java template engine (with ports for C#, Objective-C, JavaScript, Scala) for generating source code, web pages, emails, or any other formatted text output. StringTemplate is particularly good at code generators, multiple site skins, and internationalization / localization. StringTemplate also powers ANTLR.

Commons CSV reads and writes files in variations of the Comma Separated Value (CSV) format. The most common CSV formats are predefined in the CSVFormat class:

• Microsoft Excel

• Informix UNLOAD

• Informix UNLOAD CSV

• MySQL

• RFC 4180

• TDF

Custom formats can be created using a fluent style API.

Xbean-reflect provides very flexible ways to create objects and graphs of objects for dependency injection frameworks

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.

Microemulator is a Java 2 Micro Edition (J2ME) CLDC/MIDP Emulator. It demonstrates MIDlet based applications in web browser applet and can be run as a standalone java application.

HttpCore is a set of low level HTTP transport components that can be used to build custom client and server side HTTP services with a minimal footprint. HttpCore supports two I/O models: blocking I/O model based on the classic Java I/O and non-blocking, event driven I/O model based on Java NIO.

This package provides the blocking I/O model library.
