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 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 support for the Eclipse extension registry.

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

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.

Kafka is a distributed streaming platform, which means:

• it can publish and subscribe to streams of records;

• it can store streams of records in a fault-tolerant way;

• it can process streams of records as they occur.

OpenJFX is a client application platform for desktop, mobile and embedded systems built on Java. Its goal is to produce a modern, efficient, and fully featured toolkit for developing rich client applications. This package contains base classes for the OpenJFX distribution.

Bnd is a swiss army knife for OSGi, it creates manifest headers based on analyzing the class code, it verifies the project settings, it manages project dependencies, gives diffs jars, and much more.

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.

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.

Hdrhistogram creates histograms that support recording and analyzing sampled data value counts across a configurable integer value range with configurable value precision within the range. Value precision is expressed as the number of significant digits in the value recording, and provides control over value quantization behavior across the value range and the subsequent value resolution at any given level.

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.

This package contains runtime libraries for Xbase languages such as Xtend.

JSON Processing (JSON-P) is a Java API to process (e.g. parse, generate, transform and query) JSON messages. It produces and consumes JSON text in a streaming fashion (similar to StAX API for XML) and allows building a Java object model for JSON text using API classes (similar to DOM API for XML).

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 the runtime library used with generated sources by ANTLR.

JCommander is a very small Java framework that makes it trivial to parse command line parameters. Parameters are declared with annotations.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains the compendium specification module, providing interfaces and classes for use in compiling bundles.

This package provides versions of the JavaMail API implementation, IMAP, SMTP, and POP3 service providers, some examples, and documentation for the JavaMail API.

Contracts for Java, or Cofoja for short, is a contract programming framework and test tool for Java, which uses annotation processing and bytecode instrumentation to provide run-time checking. (In particular, this is not a static analysis tool.)

Jansi is a Java library that allows you to use ANSI escape sequences to format your console output which works on every platform.

LZ4 - Java is a Java port of the popular lz4 compression algorithms and xxHash hashing algorithm.

This package is a Maven plugin to generate Plexus descriptors from source tags and class annotations.

OSGi, for Open Services Gateway initiative framework, is a module system and service platform for the Java programming language. This package contains an interface for a function that accepts a single argument and produces a result.
