It's written in the documentation. "Phantom references are most often used for scheduling pre-mortem cleanup actions in a more flexible way than is possible with the Java finalization mechanism."
In reality, in 10 years of programming, it has never been needed and has never been used. I think that is suitable for some tricky release of native resources. A kind of advanced finalize.
