You probably don't want to call deepCopy during init. Also, if your
CustomFilter extends WrappingIterator, the above implementation of deepCopy
will not help because WrappingIterator.deepCopy throws
UnsupportedOperationException. So maybe that's not the problem, anyway.
Are you calling super.init at the beginning of your init method?
