Upgrade the bundled JDK version to 25 LTS

Không có tệp hoặc kiểm thử nào được nêu tên; trước tiên hãy xác định điểm vào của cấu hình hoặc bản build chọn JDK được đóng gói, rồi kiểm tra cách extension đóng gói nó. Xác minh rằng bundle kết quả sử dụng JDK 25 LTS và khởi động thành công với UseCompactObjectHeaders.
