Hello,
I ran your test class and it worked fine. Since there is no linkage
between the 1000 instances you are creating, I see no reason for a
stack overflow. I even added some code to link a tabela to its pai
(father, if babel fish is right). That still does not produce a stack
overflow...
Are you actually getting the stack overflow with the simple test case
you posted? If so, as Craig asked, can you post the full stacktrace?
Also, could you post your schema?
