------------------------------------------
Summary: FastArrayList.toString() fails to check for reference to
itself
Key: COLLECTIONS-423
URL: https://issues.apache.org/jira/browse/COLLECTIONS-423
Project: Commons Collections
Issue Type: Bug
Components: List
Affects Versions: 3.2.1
Environment: All environments
Reporter: Michael Pradel
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.
