Since BooleanClause is > using its query field for the hash code too, it can happen that the "wrong" > hash code is stored, since adding the clause to the set triggers its > hashCode(). > If assertions are enabled the check in BooleanQuery, which recomputes the > hash code, will notice it and throw an error. > exception: > {code:java} > java.lang.AssertionError > at org.apache.lucene.search.BooleanQuery.hashCode(BooleanQuery.java:614) > at java.base/java.util.Objects.hashCode(Objects.java:103) > at java.base/java.util.HashMap$Node.hashCode(HashMap.java:298) > at java.base/java.util.AbstractMap.hashCode(AbstractMap.java:527) > at org.apache.lucene.search.Multiset.hashCode(Multiset.java:119) > at java.base/java.util.EnumMap.entryHashCode(EnumMap.java:717) > at java.base/java.util.EnumMap.hashCode(EnumMap.java:709) > at java.base/java.util.Arrays.hashCode(Arrays.java:4498) > at java.base/java.util.Objects.hash(Objects.java:133) > at > org.apache.lucene.search.BooleanQuery.computeHashCode(BooleanQuery.java:597) > at org.apache.lucene.search.BooleanQuery.hashCode(BooleanQuery.java:611) > at java.base/java.util.HashMap.hash(HashMap.java:340) > at java.base/java.util.HashMap.put(HashMap.java:612) > at org.apache.lucene.search.Multiset.add(Multiset.java:82) > at org.apache.lucene.search.BooleanQuery.<init>(BooleanQuery.java:154) > at org.apache.lucene.search.BooleanQuery.<init>(BooleanQuery.java:42) > at > org.apache.lucene.search.BooleanQuery$Builder.build(BooleanQuery.java:133) > {code} > I noticed this while trying to upgrade the NetBeans maven indexer modules > from lucene 5.x to 8.x https://github.com/apache/netbeans/pull/3558 -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
