HI~ nice meet you. I have a guestion!.

I use WeakReference in my LockManager Class. Here,

But,I got a Type-Safe Warning When I compiled this.!!

Note: uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details.

Then, I modified Map.

As expected,It is the same as this.

Now,How do i fix this(Type-safe warning)? Please,Help me.
