/**
 * This is the Base class for all runtime exceptions.
 *
 * <p>In the {@link org.jcoderz.commons package overview} you can find a
 * general statement when to use runtime exceptions.</p>
 *
 * <p>This class can never be directly used. Services must implement a
 * general service specific Exception from which they can derive more
 * concrete service specific exceptions. There are some common used
 * exceptions available as direct subclasses of this class. If
 * appropriate this classes must be used prior generating own
 * classes.</p>
 *
 * <p>Most functionality is implemented and documented by the
 * {@link org.jcoderz.commons.LoggableImpl} which is used a member of
 * objects of this class. Other stuff is handled by the base class
 * {@link java.lang.Exception}.</p>
