A question about getting object address with sun.misc.Unsafe class

[James]

Dear all,

I'm wondering why sun.misc.Unsafe class allow us getting address of an
object. I'm assuming that address will be changed by GC so it's really
UNSAFE to use that address in any situation.

Is there any useful usage of this object address from using UnSafe
class?

Thanks a lot!

I think serialisation uses it. It might be useful in debugging.
