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.

Plexus classworlds replaces the native ClassLoader mechanism of Java. It is especially useful for dynamic loading of application components.

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

JCS is a distributed caching system written in Java. It is intended to speed up applications by providing a means to manage cached data of various dynamic natures. Like any caching system, JCS is most useful for high read, low put applications. Latency times drop sharply and bottlenecks move away from the database in an effectively cached system.

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.

This package contains general purpose annotations for the Jackson Data Processor, used on value and handler types. The only annotations not included are ones that require dependency to the Databind package.

The Plexus project provides a full software stack for creating and executing software projects. Based on the Plexus container, the applications can utilise component-oriented programming to build modular, reusable components that can easily be assembled and reused. This package provides the Maven plugin generating the component metadata.

This package provides the common Eclipse runtime.

This package provides the Eclipse content mechanism in the org.eclipse.core.contenttype module.

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.

The Apache Commons Compress library defines an API for working with compressed files such as ar, cpio, Unix dump, tar, zip, gzip, XZ, Pack200, bzip2, 7z, arj, lzma, snappy, DEFLATE, lz4 and Z files.

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

OPS4J stands for Open Participation Software for Java. This package contains utilities for obtaining services via the Java SE 6 ServiceLoader.

The Java Collections Framework is the recognised standard for collection handling in Java. Commons-Collections seek to build upon the JDK classes by providing new interfaces, implementations and utilities. There are many features, including:

• Bag interface for collections that have a number of copies of each object

• BidiMap interface for maps that can be looked up from value to key as well and key to value

• MapIterator interface to provide simple and quick iteration over maps

• Transforming decorators that alter each object as it is added to the collection

• Composite collections that make multiple collections look like one

• Ordered maps and sets that retain the order elements are added in, including an LRU based map

• Reference map that allows keys and/or values to be garbage collected under close control

• Many comparator implementations

• Many iterator implementations

• Adapter classes from array and enumerations to collections

• Utilities to test or create typical set-theory properties of collections such as union, intersection, and closure.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the names for the attributes and directives for a service namespace.
