Uwe Schindler commented on LUCENE-1263: --------------------------------------- The issue is definitely fixed: - since 2.9 we do per-segment searches, so MultiReader's norms cache is no longer used - and even before 2.9, at some time we changed the Hashtable to a HashMap that allowed null keys and null values. > NullPointerException in java.util.Hashtable from executing a Query > ------------------------------------------------------------------ > > Key: LUCENE-1263 > URL: https://issues.apache.org/jira/browse/LUCENE-1263 > Project: Lucene - Java > Issue Type: Bug > Components: Search > Affects Versions: 2.1 > Reporter: Benjamin Pasero > Priority: Minor > > Lately we are seeing this stacktrace showing up when executing a Query.
