-----------------------------------
Hi Krishna,
I doubt you'll see much on a closed ticket - I'd suggest either mailing the
user@ list to see if anyone else has had the problem; or if at all possible it
would be great if you could chop away at your business objects a bit and create
a reusable test case.
In either case - please feel free to open a new issue up rather than using the
old one.

> Hi,
> The ToStringBuilder throws a StackOverflowError if you have a cycle in the
> object graph. For instance, the following toString() method will cause a
> StackOverflowError:
> public class ObjectCycle {
> Object obj;
>
> public String toString() {
> return new ToStringBuilder(this).append(obj).toString();
> }
> }
> public void testObjectCycle() {
> ObjectCycle a = new ObjectCycle();
> ObjectCycle b = new ObjectCycle();
> a.obj = b;
> b.obj = a;
> a.toString(); // ouch: StackOverflowError
> }
> I'll submit some patches that fixes this problem...
> regards,
> Maarten
