Why this limit of 2^28 elements ?

I use XML to store all the elements and objects of my application,

because I want to have a "pérenne" solution. (A solution that I can think it will work in years and decenies).

Should I have to implement a new kind of arrays and/or byte string that

allows to store more than 2^28 elements when I have 2^28 + 1 elements to store ?

We had this problem with large XML documents. A simple override gives your the ability to handle larger documents. Read the post for details.

As an alternative, look into using VisualWorks 64 bit.

Re: Limits

Thanks, I will try this.

I cant use 64 bit image, because OpenGL is not working on 64 bit images (as far as I know).

There’s also SegmentedCollection and its subclasses, which already allow sizes greater than 2^28. So it’s not so much a case of having to create your own array class, but more of changing the relevant parts of the system that instantiate the basic Array to instantiate e.g. LargeArray instead. Of course if you’re dealing with such large amounts of data, it’s probably worth making your own subclass optimized for your own data patterns and usage.
