> Key: LUCENE-2645
> URL: https://issues.apache.org/jira/browse/LUCENE-2645
> Project: Lucene - Java
> Issue Type: Bug
> Components: core/index
> Reporter: David Smiley
> Assignee: Michael McCandless
> Priority: Minor
> Attachments: LuceneTrunkAssertErrorReproducer.java

> StandardPostingsWriterImpl line 159 is:
> {code:java}
> assert delta > 0 || position == 0 || position == -1: "position=" + position + " lastPosition=" + lastPosition; // not quite right (if pos=0 is repeated twice we don't catch it)
> {code}
> I enable assertions when I run my unit tests and I've found this assertion to fail when delta is 0 which occurs when the same position value is sent in twice in arrow. Once I added RemoveDuplicatesTokenFilter, this problem went away. Should I really be forced to add this filter? I think delta >= 0 would be a better assertion.
