Eastwood Charts is an independent and open source implementation of the Google Chart API. Eastwood Charts implements most of the features from Google Charts, and adds a few of its own (such as trendline overlay, 3D effects for bar charts, and optional(!) deployment via applets). Eastwood Charts uses JFreeChart to render the charts, and is aimed at web developers that want to incorporate charts into their web pages, but can't or won't send their data to Google for processing. Version 1.1.0 includes the following features:
support for generating pie charts, bar charts, line charts and scatter plots, using encodings that match the Google Chart API;
software you install on your OWN server;
open source licensing under the terms of the GNU Lesser General Public Licence (LGPL, version 2.1 or later), the same licence as JFreeChart.

Jenkins CI, formerly known as "Hudson Labs".
Jenkins monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Jenkins focuses on the following two jobs:
Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Jenkins provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity.
Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Jenkins keeps those outputs and makes it easy for you to notice when something is wrong.

Maveryx is a FREE and OPEN SOURCE Test Automation Framework for functional and regression testing of Java applications.
Maveryx eliminates the “GUI Map” dependency. Testers don't have to capture (often recapture) and maintain any GUI Map. GUI objects described in the scripts are identified and located directly at runtime during the test scripts execution. Avoiding GUI Maps testers have the possibility of starting automation early in the software lifecycle, long before the application is released for testing.
GUI objects identification is performed by an “intelligent” Finder powered by a highly configurable set of searching algorithms. Maveryx supports also approximate matching to identify the GUI objects even in case of few or partial information given in the test scripts (this is typical when deriving test scripts from lacking or partial application’s specifications or in testing non-mature/early software).
Maveryx is OS independent and works with the most used free and commercial IDE such as Eclipse, NetBeans, JUnit, IBM Rational Functional Tester, etc.

XNIO is a simplified low-level I/O layer which can be used anywhere you are using NIO today. It frees you from the hassle of dealing with Selectors and the lack of NIO support for multicast sockets and non-socket I/O, while still maintaining all the capabilities present in NIO.
XNIO provides a unique and easy-to-use API for combining blocking and non-blocking operations, even on the same channel, allowing you to take advantage of the simplicity and low latency of blocking I/O while still gaining the thread-conservative benefits of non-blocking I/O.
XNIO vastly simplifies implementation of channels, opening the door to supporting higer-level transport concepts (like SSL or virtual channels) with the same simple API.
XNIO also introduces a powerful callback-based interface which can greatly simplify traditional state machine-based non-blocking applications, as well as allowing you to hit the perfect balance between throughput and latency for your application.

Reloader is a tool that enables class reloading while the JVM is still running. JReloader is a must-have tool for developers that need to change small pieces of code on-the-fly without the burden of restarting the application.
With JReloader it's even possible to reload classes with instances actively invoked by one or more threads. Current invocations will see the old code until they return. New invocations will always see the new code. Most of the time everything works fine. This all is made possible by JVMTI, an API available since Java 1.5.
Limitations
Only changes in method bodies can be reloaded. Changes in class signature are not allowed.

Neo4j is a graph database, a fully transactional database that stores data structured as graphs.
It is a mature and robust graph database that provides:
* an intuitive graph-oriented model for data representation. Instead of static and rigid tables, rows and columns, you work with a flexible graph network consisting of nodes, relationships and properties.
* a disk-based, native storage manager completely optimized for storing graph structures for maximum performance and scalability.
* massive scalability. Neo4j can handle graphs of several billion nodes/relationships/properties on a single machine and can be sharded to scale out across multiple machines.
* a powerful traversal framework for high-speed traversals in the node space.
can be deployed as a full server or a very slim database with a small
footprint (~500k jar).
* a simple and convenient object-oriented API.

InfoGrid is an open-source internet graph database. Unlike a relational database, InfoGrid represents information as nodes and edges that relate nodes. Nodes can carry properties and can be dynamically blessed with types and unblessed.
InfoGrid can be run on a variety of storage backends, including MySQL, PostgreSQL and NoSQL. InfoGrid also provides a REST-ful web frontend, user-centric identity technology, and a Probe framework for the seamless integration of external data sources.

HyperGraphDB 1.0 is a general purpose, extensible, portable, distributed, embeddable, open-source data storage mechanism. Designed specifically for artificial intelligence and semantic web projects, it can also be used as an embedded object-oriented database for projects of all sizes.
HyperGraphDB is a Java based product built on top of the Berkeley DB storage library. It can be used as a single in-process database bound to a location on the local disk or within a cluster of networked database instances communicating and sharing data in a P2P (peer-to-peer) fashion.
Key Features of HyperGraphDB include:
* Storage of generalized hypergraphs.
* Open, extensible type system.
* Basic query system and graph traversal algorithms.
* Out-of-box support for Java object storage.
* Thread-safe transactions.
* P2P framework for data distribution.

Voldemort is a distributed key-value storage system
* Data is automatically replicated over multiple servers.
* Data is automatically partitioned so each server contains only a subset of the total data
* Server failure is handled transparently
* Pluggable serialization is supported to allow rich keys and values including lists and tuples with named fields, as well as to integrate with common serialization frameworks like Protocol Buffers, Thrift, Avro and Java Serialization
* Data items are versioned to maximize data integrity in failure scenarios without compromising availability of the system
* Each node is independent of other nodes with no central point of failure or coordination
* Good single node performance: you can expect 10-20k operations per second depending on the machines, the network, the disk system, and the data replication factor
* Support for pluggable data placement strategies to support things like distribution across data centers that are geographically far apart.
