Accessing arrays directly after reading them out of a collection like a Vector 
leads to a VerifyError using Integration Build I20040907. The problem can be 
reproduced using the following code:

import java.util.Vector;
public class VMTest{
  public static void main(String[] args){
    Vector<Integer[]> v = new Vector<Integer[]>();
    Integer[] array1 = new Integer[5];
    array1[0] = new Integer(17);
    array1[1] = new Integer(42);
    v.add(array1);
    Integer twentyfour = v.get(0)[1];  // responsible for the crash
    System.out.println(twentyfour);
  }
}

Replacing the line
  Integer twentyfour = v.get(0)[1];
by the two lines
  Integer[] array2 = v.get(0);
  Integer twentyfour = array2[1];
will fix the problem, but i think the original code should work as well...

The error message is:
java.lang.VerifyError: (class: VMTest, method: main signature: 
([Ljava/lang/String;)V) Expecting to find array of objects or arrays on stack
Exception in thread "main"
