Doug Cutting commented on LUCENE-819: ------------------------------------- > why not just apply the patch and move on? Two reasons: (1) most folks consider it an error to use null for a term's text, an error that unfortunately wasn't checked in the constructor, but causes problems in the comparator, when reading and writing, etc.--basically everywhere a term is used. Your application only uses such terms in comparators, so you're only concerned about that case, but there are more cases, and if null is officially supported they should all be fixed; and (2) adding complexity to an inner-loop comparator should not be done lightly as it may have performance implications. > NullPointerException in Term.compareTo() > ---------------------------------------- > > Key: LUCENE-819 > URL: https://issues.apache.org/jira/browse/LUCENE-819 > Project: Lucene - Java > Issue Type: Bug > Components: Index > Environment: JDK 1.4 on MacOS > Reporter: Dan Zivkovic > Attachments: lucene-819.patch, lucene-819.patch, TestTerm.java > > > java.lang.NullPointerException > at org.apache.lucene.index.Term.compareTo(Term.java:84) > at > org.apache.lucene.index.TermInfosReader.getIndexOffset(TermInfosReader.java:115) > at org.apache.lucene.index.TermInfosReader.get(TermInfosReader.java:150) > at org.apache.lucene.index.SegmentReader.docFreq(SegmentReader.java:300) > at org.apache.lucene.search.IndexSearcher.docFreq(IndexSearcher.java:78) > at org.apache.lucene.search.Similarity.idf(Similarity.java:255) > at > org.apache.lucene.search.TermQuery$TermWeight.<init>(TermQuery.java:43) > at org.apache.lucene.search.TermQuery.createWeight(TermQuery.java:142) > at > org.apache.lucene.search.BooleanQuery$BooleanWeight.<init>(BooleanQuery.java:203) > at > org.apache.lucene.search.BooleanQuery$BooleanWeight2.<init>(BooleanQuery.java:330) > at > org.apache.lucene.search.BooleanQuery.createWeight(BooleanQuery.java:372) > at org.apache.lucene.search.Query.weight(Query.java:93) > at org.apache.lucene.search.Hits.<init>(Hits.java:48) > at org.apache.lucene.search.Searcher.search(Searcher.java:53) > ... -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
