Overview:

Although JavaTM has been very successful on the server-side; It has few shortcomings limiting its adoption for others domains such as real-time, embedded or high-performance applications. For these, the Javolution library provides important "pieces" missing from the JavaTM core library and making the JavaTM platform even more attractive.

Usage:

Javolution can be used as a standard OSGi bundle.

import org.osgi.framework.*;
import org.osgi.util.tracker.ServiceTracker;
public class MyActivator implements BundleActivator { 
    ServiceTracker<XMLInputFactory, XMLInputFactory> tracker; 
    public void start(BundleContext bc) throws Exception {
        tracker = new ServiceTracker<>(bc, XMLInputFactory.class, null);
        tracker.open();
        parse();
    }
    public void stop(BundleContext bc) throws Exception {
        tracker.close();
    }
    public void parse() throws XMLStreamException {
        XMLInputFactory factory = tracker.getService();  
        factory.setProperty(XMLInputFactory.IS_COALESCING, true); // Configures.
        ...
    }          
}

Or as a standard Java library (does not require OSGi runtime).

import javolution.osgi.internal.OSGiServices;
public class Main {
    public static void main(String[] args) throws XMLStreamException {
        XMLInputFactory factory = OSGiServices.getXMLInputFactory();  
        factory.setProperty(XMLInputFactory.IS_COALESCING, true); // Configures.
        ...
    }
}

Javolution publishes the following OSGi services.
