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.

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.

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.

This package contains core low-level incremental (streaming) parser and generator abstractions used by the Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format.

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains the code for a proxy to pageant.

Commons-Exec simplifies executing external processes.

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 Eclipse core expression language with the org.eclipse.core.expressions module.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the Data Transfer Objects. It is easily serializable having only public fields of primitive types and their wrapper classes, Strings, and DTOs. List, Set, Map and array aggregates may also be used. The aggregates must only hold objects of the listed types or aggregates.

OPS4J stands for Open Participation Software for Java. This package contains utilities and extensions related to environment, i18n and mime types.

This package provides the Equinox application container for Eclipse.

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

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.

This package contains annotations used during the build of the runtime library of ANTLR.

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

The Commons Lang components contains a set of Java classes that provide helper methods for standard Java classes, especially those found in the java.lang package in the Sun JDK. The following classes are included:

• StringUtils - Helper for java.lang.String.

• CharSetUtils - Methods for dealing with CharSets, which are sets of characters such as [a-z] and [abcdez].

• RandomStringUtils - Helper for creating randomised strings.

• NumberUtils - Helper for java.lang.Number and its subclasses.

• NumberRange - A range of numbers with an upper and lower bound.

• ObjectUtils - Helper for java.lang.Object.

• SerializationUtils - Helper for serializing objects.

• SystemUtils - Utility class defining the Java system properties.

• NestedException package - A sub-package for the creation of nested exceptions.

• Enum package - A sub-package for the creation of enumerated types.

• Builder package - A sub-package for the creation of equals, hashCode, compareTo and toString methods.

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.
