This package provides the Equinox application container for Eclipse.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains a repository service that contains resources.

This package provides annotations for the findbugs package. It provides packages in the javax.annotations namespace.

This package contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. It builds on core streaming parser/generator package, and uses Jackson Annotations for configuration.

Janino is a Java compiler. Janino can compile a set of source files to a set of class files like javac, but also compile a Java expression, block, class body or source file in memory, load the bytecode and execute it directly in the same JVM. janino can also be used for static code analysis or code manipulation.

Conversant Disruptor is the highest performing intra-thread transfer mechanism available in Java. Conversant Disruptor is an implementation of this type of ring buffer that has almost no overhead and that exploits a particularly simple design.

This package provides the Java development kit OpenJDK.

Xbean-reflect provides very flexible ways to create objects and graphs of objects for dependency injection frameworks

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

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.

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

Modello Java Plugin generates Java objects for the model.

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.

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

This package provides the API module of the Log4j logging framework for Java.

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

This package contains the API used by components to manipulate compilers.

This is a word-aligned compressed variant of the Java Bitset class. It provides both a 64-bit and a 32-bit RLE-like compression scheme. It can be used to implement bitmap indexes.

The goal of word-aligned compression is not to achieve the best compression, but rather to improve query processing time. Hence, JavaEWAH tries to save CPU cycles, maybe at the expense of storage. However, the EWAH scheme is always more efficient storage-wise than an uncompressed bitmap (as implemented in the BitSet class by Sun).

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.

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.

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.

Commons Math is a library of lightweight, self-contained mathematics and statistics components addressing the most common problems not available in the Java programming language or Commons Lang.
