public class DefaultItemFailureHandler
Default implementation of the ItemListenerSupport class that
writes all exceptions via commons logging. Since generics can't be used to
ensure the list contains exceptions, any non exceptions will be logged out by
calling toString on the object.
Called if an error occurs while trying to write. Will be called inside a
transaction, but the transaction will normally be rolled back. There is
no way to identify from this callback which of the items (if any) caused
