/**
 * The transformation from Errai JSON to Jackson's JSON contains the following steps:
 * <ul>/*w  w w .j a  va2 s . c  o  m*/
 * <li>For all JSON objects, recursively remove the Errai specific OBJECT_ID and ENCODED_TYPE
 * values</li>
 * <li>Keep a reference to the removed OBJECT_IDs, so back-references can be resolved</li>
 * <li>If an array is encountered, process all its elements, then remove the Errai specific
 * QUALIFIED_VALUE key, by associating its actual value with the object's key directly: "list":
 * {"^Value": ["e1","e2"]} becomes "list": ["e1","e2"]</li>
 * <li>If an enum is encountered, remove the Errai specific ENUM_STRING_VALUE key, by associating
 * its actual value with the object's key directly: "gender": {"^EnumStringValue": "MALE"} becomes
 * "gender": "MALE"</li>
 * <li>If a number is encountered, remove the Errai specific NUMERIC_VALUE key, by associating its
 * actual value with the object's key directly: "id": {"^NumValue": "1"} becomes "id": "1"</li>
 * <li>If a date is encountered, remove the Errai specific QUALIFIED_VALUE key, by associating its
 * actual value with the object's key directly and turning it into a JSON number</li>
 * <li>If EMBEDDED_JSON is encountered, turn in into standard json</li>
 * </ul>
 * 
 * @param val
 *          the JSON value to transform
 * @param key
 *          the key of the JSON value to transform
 * @param parent
 *          the parent object of the current value
 * @param objectCache
 *          a cache for removed objects, that is used to resolve backreferences
