jsch-agent-proxy is a proxy program to OpenSSH's ssh-agent and Pageant included in Putty. This component contains an implementation of USocketFactory using JNA (Java Native Access).

JOpt Simple is a Java library for parsing command line options, such as those you might pass to an invocation of javac. In the interest of striving for simplicity, as closely as possible JOpt Simple attempts to honor the command line option syntaxes of POSIX getopt and GNU getopt_long. It also aims to make option parser configuration and retrieval of options and their arguments simple and expressive, without being overly clever.

Eclipse LSP4J provides Java bindings for the Language Server Protocol and the Debug Adapter Protocol. This package contains its JSON-RPC implementation.

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.

LMAX Disruptor is a software pattern and software component for high performance inter-thread communication that avoids the need for message queues or resource locking.

JLine is a Java library for handling console input. It is similar in functionality to BSD editline and GNU readline but with additional features that bring it in par with ZSH line editor. People familiar with the readline/editline capabilities for modern shells (such as bash and tcsh) will find most of the command editing features of JLine to be familiar.

This package includes the Terminal API and implementations.

JHDF5 is a high-level API in Java for reading and writing HDF5 files, building on the libraries provided by the HDF Group.

Xerial is a set of data management libraries for the Java programming language. The ultimate goal of the Xerial project is to manage everything as database, including class objects, text format data, data streams, etc.

This package provides the Eclipse core compare support module org.eclipse.compare.core.

Woodstox is a stax XML API implementation.

Plexus IO is a set of plexus components, which are designed for use in I/O operations. This implementation using plexus components allows reusing it in maven.

Dataformat backends are used to support format alternatives to JSON, supported by default. This is done by sub-classing Jackson core abstractions.

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.

Although the java.net package provides basic functionality for accessing resources via HTTP, it doesn't provide the full flexibility or functionality needed by many applications. HttpClient seeks to fill this void by providing an efficient, up-to-date, and feature-rich package implementing the client side of the most recent HTTP standards and recommendations.

HttpCore is a set of low level HTTP transport components that can be used to build custom client and server side HTTP services with a minimal footprint. HttpCore supports two I/O models: blocking I/O model based on the classic Java I/O and non-blocking, event driven I/O model based on Java NIO.

This package provides the non-blocking I/O model library based on Java NIO.

The Byte Code Engineering Library (Apache Commons BCEL) is intended to give users a convenient way to analyze, create, and manipulate (binary) Java class files. Classes are represented by objects which contain all the symbolic information of the given class: methods, fields and byte code instructions, in particular.

Such objects can be read from an existing file, be transformed by a program (e.g. a class loader at run-time) and written to a file again. An even more interesting application is the creation of classes from scratch at run-time. The Byte Code Engineering Library (BCEL) may be also useful if you want to learn about the Java Virtual Machine (JVM) and the format of Java .class files.

OPS4J stands for Open Participation Software for Java. This package contains utilities for storing and retrieving data from an InputStream.
