Resolved Issues

Component	Issue	Description
SDO	Dynamic Data Object generation	New Behaviour: When an SDO Type is defined if a class can not be found corresponding to the instance class name (name of the corresponding static SDO class) then one is not created. See bug 277367 and bug 268209 for more details.

Known Issues

Component	Issue	Description
JPA	JPA 2.0 - Updating Element Collection of Embeddables	With weaving enabled, updates on an element collection of embeddables can potentially throw a null pointer exception. There are two work arounds. 1) Add the annotation @ChangeTracking(DEFFERED) on the embeddable and set the following property eclipselink.weaving.internal to false. OR 2) set the following properties to false in persistence XML: eclipselink.weaving.changetracking and eclipselink.weaving.internal. Please see bug 296606 for more details about the issue and the workarounds.
Utils - Workbench	Unable to open saved Workbench projects	There is a bug in the 2.0 Workbench that prevents the Workbench project metadata from being correctly written out. The workaround is to use an EclipseLink 2.0.1 nightly build to run the Workbench. You can use this with the EclipseLink 2.0.0 runtime. The nightly builds are located here: http://www.eclipse.org/eclipselink/downloads/nightly.php. Please see bug 298300 for more information.

All known issues with EclipseLink are tracked in the Eclipse bugzilla database. Queries for current open bugs in EclipseLink are available here.
