Apache Commons Text is a library focused on algorithms working on strings.

This is a part of the Apache Commons Project.

This package provides the Java development kit OpenJDK.

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.

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

This is the GNU servlet API distribution, part of the ClasspathX project. It provides implementations of version 3.0 of the servlet API and version 2.1 of the Java ServerPages API.

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

This package provides the Java development kit OpenJDK.

ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees.

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.

This library implements concurrent data structures that are not natively available in Java.

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.

JEXL is a library intended to facilitate the implementation of dynamic and scripting features in applications and frameworks written in Java. JEXL implements an Expression Language based on some extensions to the JSTL Expression Language supporting most of the constructs seen in shell-script or ECMAScript. Its goal is to expose scripting features usable by technical operatives or consultants working with enterprise platforms.

Commons-compiler contains an API for janino, including the IExpressionEvaluator, IScriptEvaluator, IClassBodyEvaluator and ISimpleCompiler interfaces.

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 non-blocking I/O model library based on Java NIO.

TLA+ is a high-level language for modeling programs and systems---especially concurrent and distributed ones. It's based on the idea that the best way to describe things precisely is with simple mathematics. TLA+ and its tools are useful for eliminating fundamental design errors, which are hard to find and expensive to correct in code.

The following TLA+ tools are available in this distribution:

• The Syntactic Analyzer: A parser and syntax checker for TLA+ specifications;

• TLC: A model checker and simulator for a subclass of "executable" TLA+ specifications;

• TLATeX: A program for typesetting TLA+ specifications;

• Beta test versions of 1-3 for the TLA+2 language; and

• The PlusCal translator.

This package provides the Java development kit OpenJDK.

Commons-dbcp allows you to share a pool of database connections between users. Creating a new connection for each user can be time consuming and even unfeasible when the number of simultaneous users is very large. This package provides a way to share a poole of connections to reduce that load.

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.

Byte Buddy is a code generation and manipulation library for creating and modifying Java classes during the runtime of a Java application and without the help of a compiler.

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.

SLF4J binding for the JDK14 java.util.logging framework.

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.

OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to resolving properties from different sources.

Sisu is a modular JSR330-based container that supports classpath scanning, auto-binding, and dynamic auto-wiring. Sisu uses Google-Guice to perform dependency injection and provide the core JSR330 support, but removes the need to write explicit bindings in Guice modules. Integration with other containers via the Eclipse Extension Registry and the OSGi Service Registry is a goal of this project.
