• High performance and time-deterministic (real-time) util / lang / text / io / xml base classes.
• Context programming in order to achieve true separation of concerns (logging, performance, etc).
• A testing framework addressing not only unit tests but also performance and regression tests as well.
• Straightforward and low-level parallel computing capabilities with ConcurrentContext.
• Struct and Union base classes for direct interfacing with native applications (e.g. C/C++).
• World's fastest and first hard real-time XML marshalling/unmarshalling facility.
• Simple yet flexible configuration management of your application.

1. Javolution classes are simple to use, even simpler than most JDK classes. You don't need to guess the capacity of a TextBuilder, FastTable or a FastMap, their size expand gently without ever incurring expensive resize/copy or rehash operations (unlike StringBuilder, ArrayList or HashMap).
   
2. Developers may achieve true separation of concerns (e.g. logging, configuration) through Context Programming or by using classes such as Configurable.
3. Javolution classes are fast, very fast (e.g. Text insertion/deletion in O[Log(n)] instead of O[n] for standard StringBuffer/StringBuilder).
   
4. All Javolution classes are hard real-time compliant and have highly deterministic behavior (in the microsecond range). Furthermore (unlike the standard library), Javolution is RTSJ safe (no memory clash or memory leak when used with Java Real-Time extension).
   
5. Javolution makes it easy for concurrent algorithms to take advantage of multi-processors systems.
   
6. Javolution's real-time collection classes (map, list, table and set) can be used in place of most standard collection classes and provide numerous additional capabilities.
   
7. Any Java class can be serialized/deserialized in XML format in any form you may want, also no need to implement Serializable or for the platform to support serialization
8. Javolution provides Struct and Union classes for direct interoperability with C/C++ applications.
   
9. Javolution runs on any platform from the simplest J2ME CLDC 1.0 with no garbage collector to the latest J2EE 5.0 with parameterized types.
   
10. Javolution is a pure Java Solution (no native code), small (less than 300 KBytes jar file) and free; permission to use, copy, modify, and distribute this software is freely granted, provided that copyright notices are preserved (BSD License).

• August 19, 2007: Javolution 5.2
  
  • Minor changes/fixes [5.2.6]
  • Corrected FastComparator.STRING for fast hash code calculation of java.lang.String [5.2.5]
  • Fully time deterministic Java paper presented to AIAA Space 2007 conference
  • Added the WebServiceClient base class (no WSDL file required) [5.2.4]
  • Corrected issues in FastTable and FastMap [5.2.3] [5.2.4]
  • Support for custom FastMap.Entry and custom FastList.Node [5.2.2]
  • Enhanced FastMap and FastTable implementation (with an impressive performance) [5.2.2]
  • Corrected class loading circularity issue (AllocatorContext) [5.2.1]
  • New testing package to facilitate testing and code benchmark [5.2.0]
  • Added convenience method to retrieve an ObjectFactory implementation for any class (ObjectFactory.getInstance(Class)) [5.2.0]
  • Default context implementations (e.g. LogContext, StackContext, HeapContext) are now configurable [5.2.0]

• July 4, 2007: Javolution 5.1
  
  • Simplified concurrent contexts to accept any Runnable [5.1.0]
  • Enhanced documentation of Configurable [5.1.0]
  • Optimization of Text (now final) [5.1.0]
  • Added Text.print() and Text.println() methods to output Text instances without creating intermediate String instances [5.1.0]
  • Corrected error when parsing character references (XMLStreamReaderImpl) [5.1.0]
  • Added method to force the size of a FastTable [5.1.0]
  • Added static method to set/get the TextFormat associated to any particular class/interface [5.1.0]
  • Any type for which the TextFormat is known can be represented as a XML attribute [5.1.0]

• May 6, 2007: Javolution 5.0
  Major Relase! Here are the most important changes:
  • Separation of concerns: Two new contexts have been added, the AllocatorContext and the SecurityContext.
  • The PoolContext (too generic) has been replaced by the StackContext whose implementation can be based on thread-local queues (default) or ScopedMemory (RTSJ).
  • The RealtimeObject base class is superceeded by the Realtime interface.
  • New ValueType interface for immutable objects which can be referenced by copy and can always be allocated on the "stack"!
  • New ArrayFactory to allocates/recycle variable sizes arrays. "Stack" allocation is independent from the array's size and significantly faster than "heap" allocation.
