 - the extra AOP stuff was removed (aopalliance/cglib), no intercepting any more
 - removed all logging, uses of java.util.logger.* stuff and logger default binding
 - removed all java.io.Serializable dependent stuff. Note: everything which relies to be serializable was removed.
 - reformatted source by IntelliJ and cleaned up source of @author and @since tags
