Class UtilActivator

java.lang.Object
  net.java.sip.communicator.util.UtilActivator

All Implemented Interfaces:

Thread.UncaughtExceptionHandler, org.osgi.framework.BundleActivator

public class UtilActivator
extends Object
implements org.osgi.framework.BundleActivator, Thread.UncaughtExceptionHandler

The only raison d'etre for this Activator is so that it would set a global exception handler. It doesn't export any services and neither it runs any initialization - all it does is call Thread.setUncaughtExceptionHandler()
