Mar 1, 2026March 2026 monthly summary for OpenLiberty/open-liberty: delivered cross-database platform enhancements and relevant fixes across DB2, PostgreSQL, SQL Server, and Jakarta EE/JPA 3.1 compatibility. Key outcomes include the introduction of database-specific platform classes (DB2Platform, PostgreSQLPlatform, SQLServerPlatform) to enable native behaviors and optimized DDL, UUID mapping improvements, and robust DDL compatibility in FAT tests. Resolved critical issues such as non-null/non-empty suffix handling in field type size printing and UUID field mapping for SQL Server, along with compatibility updates for EclipseLink 5 in JPA 3.1 tests. These efforts improve database portability, reliability, and performance of ORM-to-DB mappings, streamline cross-DB deployments, and strengthen Jakarta EE 3.1 readiness.

Feb 1, 2026February 2026 OpenLiberty contributions focused on enhancing expression handling and concurrency, delivering an overlay architecture for expression operators and reinforcing thread-safety across core components in the OpenLiberty/open-liberty repository. Key changes include: new ExpressionOperator overlay enabling additional SQL expressions, refactors to ArgumentListFunctionExpression and DB2Platform to remove shared state and improve concurrency, and copyright header updates to reflect the current year. These efforts improve flexibility for complex SQL operations, stabilize multi-threaded execution, and support maintainability and future extensibility.
