The heck?


Type1[][] backup = (Type1[][])this.original.clone();

/*
 * Some processing going on in original array
 *
 *
 * For debugging purposes I check backup and it has change
 */

this.original = backup; //no that important; backup changed before this

Can anybody hint out what's happening. I didn't touch backup in the whole processing. Isn't clone supposed to create new clone instead of just copying over the reference variable? Or do I perhaps need to override clone() with a custom method because perhaps it doesn't work properly with custom types (such as type1 above)? Or am I just talking bunkers?   I
