Commit 09d1d1a958124c22acc08328336f49306d65dc24 in openjpa's branch 
refs/heads/OPENJPA-2940 from Richard Zowalla

[OPENJPA-2940] Emulate NULLS FIRST/LAST on MySQL/MariaDB

MySQL and MariaDB don't support ANSI 'NULLS FIRST' / 'NULLS LAST' on
ORDER BY. Route the ordering-suffix emission through
DBDictionary.appendNullsPrecedence so dialects can customize.

Default implementation emits 'NULLS FIRST' / 'NULLS LAST' unchanged.
MySQLDictionary and MariaDBDictionary override to emulate via the
'<expr> IS NULL <sort>' auxiliary sort key. The emulation is skipped
when MySQL's default NULL ordering (NULLs first for ASC, NULLs last for
DESC) already matches the requested precedence.

> Implement Jakarta Persistence API 3.2 as prescribed by 
> [specification|https://jakarta.ee/specifications/persistence/3.2/] and 
> required by Jakarta EE 11.
> This change requires JDK17 or higher compatibility and needs considerable 
> checks.
> I've already pushed a branch (WIP) without the proper API bump, focusing on 
> updating dependencies while keeping the project passing its current tests at 
> least in default profile.
