Javolution is a real-time library aiming to make Java applications faster and more time predictable. Indeed, time-predictability can easily be ruined by the use of the standard library (lazyinitialization, array resizing, etc.) which is not acceptable for safety-critical systems. The open source Javolution library addresses these concerns for the Java platform (ref. [http://javolution.org/doc/AIAA-2007-6184.pdf Fully Time Deterministic Java] ) and provides numerous high-performance classes and utilities useful to non real-time applications as well. Such as:

* Algorithmic parallel computing support with [http://javolution.org/api/javolution/context/ConcurrentContext.html concurrent contexts] .

* High performance implementation of standard Java packages (such as the [http://javolution.org/api/javolution/util/package-summary.html#package_description javolution.util] package holding real-time [http://java.sun.com/j2se/1.5.0/docs/api/java/util/package-summary.html java.util] collections implementations).

* [http://javolution.org/api/javolution/context/package-summary.html#package_description Context] programming in order to achieve true separation of concerns (logging, performance, etc).

* [http://javolution.org/api/javolution/lang/ValueType.html ValueType] and [http://javolution.org/api/javolution/context/StackContext.html Stack] allocation support (thread-local pools or RTSJ ScopedMemory).

* [http://javolution.org/api/javolution/io/Struct.html Struct] and [http://javolution.org/api/javolution/io/Union.html Union] base classes for direct interfacing with native applications.

* Real-Time StAX implementation ( [http://www.javolution.org/api/javolution/xml/stream/package-summary.html#package_description javolution.xml.stream] ) which does not force object creation.

* XML [http://javolution.org/api/javolution/xml/package-summary.html#package_description marshalling/unmarshalling] working with existing Java classes and supporting references (including circular references).

* Simple yet powerful [http://javolution.org/api/javolution/lang/Configurable.html configuration management] for your application.

The library is also fully RTSJ compliant (does not cause memory clash or illegal access error with RTSJ Virtual Machines).
