How do I get the instance of sun.misc.Unsafe?

java, unsafe

Solution

From baeldung.com, we can get the instance using reflection:

   Field f =Unsafe.class.getDeclaredField("theUnsafe");
   f.setAccessible(true);
   unsafe = (Unsafe) f.get(null);

Problem

How do I get the instance of the unsafe class? I always get the security exception. I listed the code of the OpenJDK 6 implementation. I would like to mess around with the function `sun.misc.Unsafe` offers to me, but I always end up getting the `SecurityException("Unsafe")`. ``` public static Unsafe getUnsafe() { Class cc = sun.reflect.Reflection.getCallerClass(2); if (cc.getClassLoader() != null) throw new SecurityException("Unsafe"); return theUnsafe; } ``` (Please don't try to tell me how unsafe it is to use this class.)
