It called by grpc, I'm not sure whether new version grpc solve this problem.

Maybe we can try to upgrade grpc version, but if grpc don't fix it, it will waring still.

[xingjian]

OK. Understood. Thank you for your answer.

[KomachiSion]

grpc already upgrade in 3.1.2 ， please retry in new version and if problem still exist, please submit new issue and link to this issue.

Still reproducing with nacos-client 3.2.3 on JDK 25:

WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
WARNING: sun.misc.Unsafe::allocateMemory has been called by com.alibaba.nacos.shaded.io.grpc.netty.shaded.io.netty.util.internal.PlatformDependent0$2 (file:/D:/maven/resp/com/alibaba/nacos/nacos-client/3.2.3/nacos-client-3.2.3.jar)

As suggested in the closing comment, I retried with 3.2.3 (newer than 3.1.2), but the allocateMemory warning from the shaded Netty PlatformDependent0 still appears on every startup.

Since Unsafe::allocateMemory is part of Netty's off-heap allocation path, upgrading grpc/netty alone does not seem to remove the call itself. Is there any plan to address this in a future release, or is --sun-misc-unsafe-memory-access=allow the only workaround for JDK 25 users?
