- All Fixed Bugs and enhancement requests
Property Name Generation from Introspector.decapitalize
The decapitalize method will now leave the property name in uppercase if the first and second characters are uppercase. EclipseLink will use the property name as ID, as detailed in the specification.
Note that this may require a change in some JPQL. For example, if previously you had a method with an annotation such as getcCustomers that would have properties named cCustomers, you will now have Customers.
In EclipseLink 2.2 the following features/API have been deprecated. Please upgrade to the suggested alternatives to avoid issues in the future when these deprecated features/AIP might be removed.
|ObjectCopyPolicy||The ObjectCopyPolicy has been replaced with the CopyGroup. The full API from ObjectCopyPolicy is supported by CopyGroup requiring only a minor class name change in user code.|
|ObjectLevelReadQuery.addPartialAttribute||Partial attribute queries have been deprecated and replaced with the use of FetchGroup|
|ReadObjectQuery.selectionKey (Vector)||Replaced with the use of an object for single part keys and a CacheId for composite keys. The replacement API is: ReadObjectQuery#selectionId.|
|BasicMap, BasicCollection, CollectionTable||Deprecated in 2.0, these native mappings and supported configuration annotations are now supported by JPA 2.0's ElementCollection mapping and supported configuration annotations and orm.xml.|
TODO: Was any previously deprecated functionality removed or any functionality that could not be deprecated first removed?
The EclipseLink 2.2 (Helios) release will remain available for download from the primary download page until the next release is shipped. At that point it will be moved to the previous releases where it remain for a minimum period of 2 years before becoming available for archival.
