Using Unsafe to break encapsulation - step 1

Step1.java

    public static final Unsafe unsafe;
    static
    {
        try
        {
            // This is a bit of voodoo to force the unsafe object into
            // visibility and acquire it.
            // This is not playing nice, but as an established back door it is
            // not likely to be taken away.
            Field field = Unsafe.class.getDeclaredField("theUnsafe");
            field.setAccessible(true);
            unsafe = (Unsafe)field.get(null);
        }
        catch (Exception e)
        {
            throw new RuntimeException(e);
        }
    }
