+ * two methods:
+ * <ul>
+ *   <li>{@link java.sql.Connection#close()} - returns the connection to the
+ *       pool then breaks the link between cutoff and the next interceptor.
+ *       May be called multiple times.</li>
+ *   <li>{@link java.lang.Object#toString()} - returns a custom string for this
+ *       object</li>
+ * </ul>
+ * By default method comparisons is done on a String reference level, unless the
+ * {@link PoolConfiguration#setUseEquals(boolean)} has been called with a
