OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to java.lang.

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.

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

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the definition of common types in osgi packages.

This project contains API and Compatible Implementation of Jakarta JSON Processing specification. Jakarta JSON Processing provides portable APIs to parse, generate, transform, and query JSON documents.

JUnit is a simple framework to write repeatable tests for Java projects. JUnit provides assertions for testing expected results, test fixtures for sharing common test data, and test runners for running tests.

Joda-Time is a replacement for the Java date and time classes prior to Java SE 8.

The Bean Scripting Framework (BSF) is a set of Java classes which provides scripting language support within Java applications, and access to Java objects and methods from scripting languages. BSF allows one to write JSPs in languages other than Java while providing access to the Java class library. In addition, BSF permits any Java application to be implemented in part (or dynamically extended) by a language that is embedded within it. This is achieved by providing an API that permits calling scripting language engines from within Java, as well as an object registry that exposes Java objects to these scripting language engines.

Apache Felix is a community effort to implement the OSGi Framework and Service platform.

This package provides the Eclipse core compare support module org.eclipse.compare.core.

The codec package contains simple encoder and decoders for various formats such as Base64 and Hexadecimal. In addition to these widely used encoders and decoders, the codec package also maintains a collection of phonetic encoding utilities.

This is a part of the Apache Commons Project.

This package provides an extension to earlier versions of easymock that allows mocking classes.

This package provides the Java development kit OpenJDK.

JAX-RS provides a standardized API for building RESTful web services in Java.

Xerial is a set of data management libraries for the Java programming language. The ultimate goal of the Xerial project is to manage everything as database, including class objects, text format data, data streams, etc.

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.

This package provides the native library for jansi, a small Java library that allows you to use ANSI escape sequences to format your console output.

The files in this collection implement JSON encoders/decoders in JavaScript.

json2.js: This file creates a JSON property in the global object, if there isn't already one, setting its value to an object containing a stringify method and a parse method. The parse method uses the eval method to do the parsing, guarding it with several regular expressions to defend against accidental code execution hazards. On current browsers, this file does nothing, preferring the built-in JSON object.

json_parse.js: This file contains an alternative JSON parse function that uses recursive descent instead of eval.

json_parse_state.js: This files contains an alternative JSON parse function that uses a state machine instead of eval.

cycle.js: This file contains two functions, JSON.decycle and JSON.retrocycle, which make it possible to encode cyclical structures and DAGs in JSON, and to then recover them. This is a capability that is not provided by ES5. JSONPath is used to represent the links.

This package provides Romanian stemmers and stopwords for the Lunr Javascript library.

This package provides French stemmers and stopwords for the Lunr Javascript library.

Selectize is the hybrid of a textbox and <select> box. It's jQuery based and it has autocomplete and native-feeling keyboard navigation; it is useful for tagging, contact lists, etc.

MathJax is a JavaScript display engine for LaTeX, MathML, and AsciiMath notation that works in all modern browsers. It requires no plugins or software to be installed on the browser. So the page author can write web documents that include mathematics and be confident that readers will be able to view it naturally and easily.

RequireJS loads plain JavaScript files as well as more defined modules. It is optimized for in-browser use, including in a Web Worker, but it can be used in other JavaScript environments.

This package provides Chinese stemmers and stopwords for the Lunr Javascript library.
