	and browsers coded in 100% Managed Verifiable code

No you dont.

Arrays are all bounds checked; ..., that is, the following code will
throw an exception:

================================
class Foo {
  static {
    int[] m = new int[2];
    System.out.println(m[34]);
  }
}
================================


What do you mean by "overflow"? Do you mean this?

================================
class Foo {
  static {
    int m = Integer.MAX_VALUE;
    int k = Integer.MAX_VALUE + Integer.MAX_VALUE;
    System.out.println(m);
    System.out.println(k);
    System.exit(0);
  }
}
================================

if so, I don't see how that is an issue.
