/**
 * Infinispan's log abstraction layer on top of JBoss Logging.
 * 
 * It contains explicit methods for all INFO or above levels so that they can
 * be internationalized. For the commons module, message ids ranging from 0901
 * to 1000 inclusively have been reserved.
 * 

 *  Log log = LogFactory.getLog( getClass() );  The above will get
 * you an instance of Log, which can be used to generate log messages
 * either via JBoss Logging which then can delegate to Log4J (if the libraries
 * are present) or (if not) the built-in JDK logger.
 * 

 * In addition to the 6 log levels available, this framework also supports
 * parameter interpolation, similar to the JDKs {@link String#format(String, Object...)}
 * method. What this means is, that the following block:
 *  if (log.isTraceEnabled()) { log.trace("This is a message " + message + " and some other value is " + value); }
 * 
 * 

 * ... could be replaced with ...
 * 

 *  if (log.isTraceEnabled()) log.tracef("This is a message %s and some other value is %s", message, value);
 * 
 * 

 * This greatly enhances code readability.
 * 

 * If you are passing a Throwable, note that this should be passed in
 * before the vararg parameter list.
 *
