GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
OWASP Zed Attack Proxy (ZAP) is an easy-to-use integrated penetration testing tool for finding vulnerabilities in Web applications. It is designed to be used by people with a wide range of security experience and as such is ideal for developers and functional testers who are new to penetration testing as well as being a useful addition to an experienced pen tester's toolbox. ZAP provides automated scanners as well as a set of tools that allow you to find security vulnerabilities manually.
nioReactor is a framework for quickly building scalable event-driven network applications. It is built on top of the Reactor design pattern using NIO sockets. This provides high performance and allows for a complete separation from the application specific code. The goal of the project is to provide a simple set of APIs that allow users to build scalable servers without needing to deal with with the cumbersome and sometimes temperamental peaces of the NIO package.
VectorGraphics2D can export Java painting operations to Encapsulated PostScript (EPS), Scalable Vector Graphics (SVG), or Portable Document Format (PDF) files. It supports the rendering of all geometric shapes provided by the Java language. More advanced features like transparency or clipping paths can be used as well. It has a very small footprint and can be easily used as a replacement for Java's java.awt.Graphics2D class.
Contracts for Java (Cofoja) adds contract programming support to Java through simple yet powerful annotations: @Requires, @Ensures, @Invariant, and @ThrowEnsures. Contracts are inherited from interfaces and superclasses and can be enabled selectively during development then disabled for release.
Overthere is a Java library to manipulate files and execute processes on remote hosts, i.e. do stuff "over there". It was built for and is used in the XebiaLabs deployment automation product Deployit as a way to perform tasks on remote hosts, e.g. copy configuration files, install EAR files, or restart Web servers. Another way of looking at it is to say that Overthere gives you java.io.File and java.lang.Process as they should have been: as interfaces, created by a factory and extensible through an SPI mechanism.
