Jaxen is an XPath library written in Java. It is adaptable to many different object models, including DOM, XOM, dom4j, and JDOM. It is also possible to write adapters that treat non-XML trees such as compiled Java byte code or Java beans as XML, thus enabling you to query these trees with XPath too.

Xml Pull Parser (in short XPP) is a streaming pull XML parser and should be used when there is a need to process quickly and efficiently all input elements (for example in SOAP processors). This package is in maintenance mode.

Xsdlib contains an implementation of sun.com.msv, an XML validator.

Woodstox is a stax XML API implementation.

SWT is a widget toolkit for Java designed to provide efficient, portable access to the user-interface facilities of the operating systems on which it is implemented.

Contracts for Java, or Cofoja for short, is a contract programming framework and test tool for Java, which uses annotation processing and bytecode instrumentation to provide run-time checking. (In particular, this is not a static analysis tool.)

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.

The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, log4j) allowing the end user to plug in the desired logging framework at deployment time.

jakarta-regexp is an old regular expression parser generator for Java.

This package provides annotations for security. It provides packages in the javax.annotation and javax.annotation.security namespaces.

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 various Java utility classes for the Plexus framework to ease working with strings, files, command lines, XML and more.

OPS4J stands for Open Participation Software for Java. This package contains utilities for storing and retrieving data from an InputStream.

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains an implementation of USocketFactory using netcat.

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 metatype.

Error Prone is a static analysis tool for Java that catches common programming mistakes at compile-time. This package contains annotations used by programmers to guide the static analysis.

This package is a library to help creating CLI around Plexus components.

JSON Processing (JSON-P) is a Java API to process (e.g. parse, generate, transform and query) JSON messages. It produces and consumes JSON text in a streaming fashion (similar to StAX API for XML) and allows building a Java object model for JSON text using API classes (similar to DOM API for XML).

Java Compiler Compiler (JavaCC) is the most popular parser generator for use with Java applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc.

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.

This package contains the runtime library used with generated sources by ANTLR.

This package is the jaxb annotations module for jackson.

Pure Java implementation of the NaCl: Networking and Cryptography library.

This library is used in the legacy build process of several key frameworks developed by ObjectWeb, among them legacy versions of the ObjectWeb ASM bytecode manipulation framework.
