 * number of possible underlying causes, including
 * <ul>
 * <li>failure of a security check
 * <li>an exception occurring inside the getter or setter method
 * <li>a nullable database column was mapped to a primitive-type property
 * <li>the Hibernate type was not castable to the property type (or vice-versa)
