JamVM is a Java Virtual Machine conforming to the JVM specification edition 2 (blue book). It is extremely small. However, unlike other small VMs it supports the full spec, including object finalisation and JNI.

Ant is a platform-independent build tool for Java. It is similar to make but is implemented using the Java language, requires the Java platform, and is best suited to building Java projects. Ant uses XML to describe the build process and its dependencies, whereas Make uses Makefile format.

Tukaani-xz is an implementation of xz compression/decompression algorithms in Java.

Snappy-java is a Java port of snappy, a fast C++ compressor/decompressor.

Jbzip2 is a Java bzip2 compression/decompression library. It can be used as a replacement for the Apache CBZip2InputStream / CBZip2OutputStream classes.

Snappy-java is a Java port of snappy, a fast C++ compressor/decompressor.

Iq80-snappy is a port of the Snappy compressor and decompressor rewritten in pure Java. This compression code produces a byte-for-byte exact copy of the output created by the original C++ code, and is extremely fast.

Zstd, short for Zstandard, is a lossless compression algorithm, which provides both good compression ratio and speed for standard compression needs. This package provides JNI bindings for Zstd native library that provides fast and high compression lossless algorithm for Android, Java and all JVM languages.

FlatLaf is a cross-platform Look and Feel for Java Swing desktop applications. It looks almost flat (no shadows or gradients), clean, simple and elegant. FlatLaf comes with Light, Dark, IntelliJ and Darcula themes, scales on HiDPI displays and runs on Java 8 or newer.

The look is heavily inspired by Darcula and IntelliJ themes from IntelliJ IDEA 2019.2+ and uses almost the same colors and icons.

ditaa is a small command-line utility that converts diagrams drawn using ascii art drawings that contain characters that resemble lines like | / -), into proper bitmap graphics.

Piccolo2D is a framework (in the Jazz ZUI tradition) to create robust, full-featured graphical applications in Java, with features such as zooming and multiple representation. This package provides additional features not found in the core libraries.

Marlin is a Java2D RenderingEngine optimized for performance (improved memory usage and footprint, better multi-threading) and better visual quality based on OpenJDK's pisces implementation. It handles shape rendering (Graphics2D draw(Shape) / fill(Shape) with stroke and dash attributes.

Piccolo2D is a framework (in the Jazz ZUI tradition) to create robust, full-featured graphical applications in Java, with features such as zooming and multiple representation. This package provides the core libraries.

This addon for FlatLaf bundles many popular third party themes from JetBrains Plugins Repository into a JAR and provides Java classes to use them.

jblas is a fast linear algebra library for Java. jblas is based on BLAS and LAPACK, the de-facto industry standard for matrix computations, and uses state-of-the-art implementations for all its computational routines, making jBLAS very fast.

This package provides evaluation strategies and an implementation for RDF4J's query algebra.

This package provides language handlers used in RDF4J.

This package provides a repository implementation that uses an RDF4J SAIL stack.

This package provides an implementation of the RDF4J Rio API, which reads and writes JSON-LD.

This package provides an implementation of the RDF4J Rio API, which reads and writes NTriples.

This package provides interfaces for the RDF data model used in the RDF4J framework.

This package provides an implementation of the RDF4J Rio API, which reads and writes Turtle.

This package provides basic implementation of RDF4J's SAIL API.

The SAIL API decouples database implementations and the functional modules of the RDF4J framework.
