While the client hangs in executeBatch().
If N is 8000, the client gets the following Exception:
Exception in thread "main" org.apache.derby.client.am.BatchUpdateException:
Non-atomic batch failure. The batch was submitted, but at least one exception
occurred on an individual member of the batch. Use getNextException() to
retrieve the exceptions for specific batched elements.
