Pax Exam creates OSGi bundles for testing purposes. It lets the user take control of the OSGi framework, the test framework (e.g. JUnit) and the system under test at the same time.

LIBANTLR3C provides run-time C libraries for ANTLR3 (ANother Tool for Language Recognition v3).

BeanShell is a small, free, embeddable Java source interpreter with object scripting language features, written in Java. BeanShell dynamically executes standard Java syntax and extends it with common scripting conveniences such as loose types, commands, and method closures like those in Perl and JavaScript.

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.

TreeLayout creates tree layouts for arbitrary trees. It is not restricted to a specific output or format, but can be used for any kind of two dimensional diagram. Examples are Swing based components, SVG files, etc. This is possible because TreeLayout separates the layout of a tree from the actual rendering.

java-native-access-platform has cross-platform mappings and mappings for a number of commonly used platform functions, including a large number of Win32 mappings as well as a set of utility classes that simplify native access.

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 and helper classes for building other parts of the distribution.

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.

jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains a library to use jsch-agent-proxy with JSch.

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.

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.

BeanUtils provides a simplified interface to reflection and introspection to set or get dynamically determined properties through their setter and getter method.

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.

Drip is a launcher for the Java Virtual Machine that provides much faster startup times than the java command. The drip script is intended to be a drop-in replacement for the java command, only faster.
