ArrayCollection Mustella test failing

[Justin Mclean]

Hi,

I just noticed that one the of ArrayCollection test 
(ArrayCollection_Method_itemUpdated_contains) was failing. At first I though it 
was due to a recent changes I made to the collection classes but looks like 
it's an existing (unreported?) SDK issue.

If I run the code below compiled with Apache Flex develop branch the array 
collection length is 3 after the itemUpdated and 4 before - the mustella test 
is expecting 4 and fails. Both Adobe Flex 4.6 and Apache Flex 4.9.1 give 4 in 
both cases.

When the array is filtered you are left with jersey numbers 12, 12, 21 and 34. 
Changing playerC's jersey number to 80 (from 12) and updating the item should 
then filter it out of the collection leaving you with a total 3 items.

Anyone confirm that my logic is correct and that the test is currently wrong?

Here's the code:
