[core] Use of Object type instead of template type

[bagipro]

Hi, I've noticed an issue that prevents method resolution. Class com.samsung.knox.securefolder.util.WeakReferenceHandler

public abstract class WeakReferenceHandler<T> extends android.os.Handler {
    private java.lang.ref.WeakReference<T> mReference;

    public void handleMessage(android.os.Message message) {
        java.lang.Object obj = this.mReference.get(); // should be "T t = ..."
        if (obj != null) {
            handleMessage(obj, message);
        }
    }

    public abstract void handleMessage(T t, android.os.Message message);

there are many of them, but it could be a simple case

Fixed. Anyway many other cases with generics not yet covered.
