Information in this document applies to any platform.
When upgrading from TopLink 22.214.171.124.0 (EclipseLink 1.0.1) to TopLink 126.96.36.199.0 (EclipseLink2.0.2). a problem is encountered.
When merging an entity that has BasicCollection mapping, the existing entries of the BasicCollection is inserted again causing duplicate rows or unique key constraint violation (if the primary key is the id of the CollectionTable). This behavior changed from TopLink 188.8.131.52.0 (EclipseLink 1.0.1) to TopLink 184.108.40.206.0 (EclipseLink 2.0.2) .
