      Because unlinked collections were used by the EJB-QL compiler to store join paths of processed queries, the order of individual parts of produced SQL queries was different with different versions of the Java Development Kit. While the queries produced identical results, the differences affected execution plan performance on some database systems. With this update, the unlinked collections have been replaced with linked ones. As a result, the produced SQL queries are now identical with different Java Development Kit versions and execution plan performance is no longer affected.
