I'm using Lucene 2.9 and sometimes get a NPE in NearSpansUnordered: <java.lang.NullPointerException>java.lang.NullPointerException at org.apache.lucene.search.spans.NearSpansUnordered.start(NearSpansUnordered.java:219) at org.apache.lucene.search.payloads.PayloadNearQuery$PayloadNearSpanScorer.processPayloads(PayloadNearQuery.java:201) at org.apache.lucene.search.payloads.PayloadNearQuery$PayloadNearSpanScorer.getPayloads(PayloadNearQuery.java:180) at org.apache.lucene.search.payloads.PayloadNearQuery$PayloadNearSpanScorer.getPayloads(PayloadNearQuery.java:183) at org.apache.lucene.search.payloads.PayloadNearQuery$PayloadNearSpanScorer.setFreqCurrentDoc(PayloadNearQuery.java:214) at org.apache.lucene.search.spans.SpanScorer.nextDoc(SpanScorer.java:64) at org.apache.lucene.search.Scorer.score(Scorer.java:74) at org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:247) at org.apache.lucene.search.Searcher.search(Searcher.java:152)
The CellQueue pq is empty when this occurs. Are there any conditions in which the queue might be expected to be empty? Peter
