[jira] [Commented] (JENA-60) NiceIterator.andThen: remove() has minor bug

["Yonathan Randolph (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-60?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13021203#comment-13021203 ] 

Yonathan Randolph commented on JENA-60:
---------------------------------------

I realized that for some iterators like FilterITerator it is impossible to call remove() after hasNext(), so I guess I shouldn't expect andThen to work when you call them in the wrong order either.

> it can try to remove() from the wrong underlying iterator. Remove should call remove() on the iterator that returned the previous next(), not current.
