Hello @dmatej, @OndroMih, I've worked on this issue.
Please review the PR here #25646 and let me know in case of any adjustments

Note that:

• Java 17 - deprecated Security Manager, still works as usual
• Java 24 - Security Manager disabled - cannot be enabled but apps still run
• Java 25 - Security Manager API still present, cannot be enabled, apps still run
