Description

Harmony's ArrayList may cause data corruption.
The testcase is list as following:

ArrayList list1 = new ArrayList();
ArrayList list2 = new ArrayList();
int location = 2;

String[] strings =

{"0","1","2","3","4","5","6"}

;
int[] integers =

{0,1,2,3,4,5,6,7,8,9}

;
for (int i = 0; i < 7; i++)

{ list1.add(strings[i]); }

for (int i = 0; i < 10; i++)

{ list2.add(integers[i]); }

list1.remove(location);
list1.addAll(location,list2);

for(Object element: list1)

{ System.out.print(element+","); }

RI will print
"0", "1", 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, "3", "4", "5", "6",
While Harmony will print
"0", "1", 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, "1", "3", "4", "5",

The "6" is missing and "1" is duplicated.
