Java 25: terminally deprecated warning from sun.misc.Unsafe

[Uhuli]

Description

When using JOML 1.10.8 on a modern JDK (e.g. Java 24/25), a "terminally deprecated" warning is emitted due to the use of sun.misc.Unsafe::objectFieldOffset.

With the ongoing work on JEP 471, several memory access methods in sun.misc.Unsafe are deprecated for removal. This may cause compatibility issues or breakage in future Java releases if JOML does not migrate to supported alternatives such as VarHandle or MemorySegment.

Reference: https://openjdk.org/jeps/471

Steps to Reproduce

1. Use org.joml:joml:1.10.8
2. Run on a JDK that emits warnings for deprecated Unsafe usage (e.g. Java 25 or recent EA builds).
3. Execute code that triggers initialization of org.joml.MemUtil.

Log Output

WARNING: A terminally deprecated method in sun.misc.Unsafe has been called

WARNING: sun.misc.Unsafe::objectFieldOffset will be removed in a future release
