[jira] [Commented] (COLLECTIONS-423) FastArrayList.toString() fails to check for reference to itself

---------------------------------------------

Hi Michael,

thanks for your bug report. It is unlikely that there will be a 3.2.2 release and the FastArrayList has been dropped for future major releases (currently preparing release 4.0) in favor of CopyOnWriteArrayList which is available from the standard JDK.

> FastArrayList.toString() throws a StackOverflowError when the list contains itself, because toString() is called recursively. In contrast, ArrayList checks for this case and deals with it appropriately. E.g.:
>   ArrayList l = new FastArrayList();
>   l.add(l);
>   l.toString(); // StackOverflowError
> But:
>   ArrayList l = new ArrayList();
>   l.add(l);
>   l.toString(); // OK
> 	
> To be compatible with its superclass, FastArrayList should also consider this special case.
