------------------------------------

Yes, hopefully it will.
I have the same problem with 3.2cr4.

> The checkNaturalId() method has a bug.  Basically it's using "loaded[prop]" in the isEqual() method call but it should be using "loaded[i]".
> The value for prop is the index into the array of properties for the entity where the natural key is.  The value for i is the index in the loaded[] array that is being checked.  In my case I've got a single natural key so loaded[0] equals the natural key value, but it is located at position 1 in the properties[15] array.
> The full line, "if ( !types[prop].isEqual( current[prop], loaded[prop], entityMode ) ) {" throws ArrayIndexOOB exception since prop is 1 but only loaded[0] (i) is valid.
> The fix is quite simple, just change the line to read: "if ( !types[prop].isEqual( current[prop], loaded[i], entityMode ) ) {"
