Motivation:
- Unnecessary JNI fallback
When `Unsafe` is disabled or unavailable, but the JDK provides a usable
FFM (Foreign Function & Memory) API, the existing code still falls back
to JNI to obtain the address of a direct `ByteBuffer`.
- Incorrect FFM semantics in `PlatformDependent0#directBufferAddress`
The `Unsafe` branch returns the **base address** of the direct buffer
(index 0), consistent with JNI `GetDirectBufferAddress`.
However, the FFM branch uses `MemorySegment.ofBuffer(buffer).address()`,
which effectively returns `baseAddress + position`.
This leads to inconsistent semantics between the FFM and Unsafe/JNI
implementations.
``` java
ByteBuffer byteBuffer = ByteBuffer.allocateDirect(1024);
//ffm api
System.out.println(PlatformDependent.directBufferAddress(byteBuffer));
// jni
System.out.println(Buffer.memoryAddress(byteBuffer));
byteBuffer = byteBuffer.position(16);
System.out.println(PlatformDependent.directBufferAddress(byteBuffer));
System.out.println(Buffer.memoryAddress(byteBuffer));
```
On Java 25 and Netty 4.2.12.Final, this code prints:
```
129502193232224
129502193232224
129502193232240
129502193232224
```
The third line reflects baseAddress + 16, demonstrating that the FFM
path is position-dependent, while the JNI path remains
position-independent.
Modification:
- Prefer the FFM/JVM path when `Unsafe` is unavailable but FFM is
available, avoiding the JNI fallback.
- Fix the FFM branch to return the same **base-address semantics** as
the Unsafe/JNI paths (i.e., position-independent).
Result:
fix FFM address semantics in directBufferAddress

Motivation:
Unnecessary JNI fallback
When
Unsafeis disabled or unavailable, but the JDK provides a usable FFM (Foreign Function & Memory) API, the existing code still falls back to JNI to obtain the address of a directByteBuffer.Incorrect FFM semantics in
PlatformDependent0#directBufferAddressThe
Unsafebranch returns the base address of the direct buffer (index 0), consistent with JNIGetDirectBufferAddress.However, the FFM branch uses
MemorySegment.ofBuffer(buffer).address(), which effectively returnsbaseAddress + position.This leads to inconsistent semantics between the FFM and Unsafe/JNI implementations.
On Java 25 and Netty 4.2.12.Final, this code prints:
The third line reflects baseAddress + 16, demonstrating that the FFM path is position-dependent, while the JNI path remains position-independent.
Modification:
Unsafeis unavailable but FFM is available, avoiding the JNI fallback.Result:
fix FFM address semantics in directBufferAddress
