[jira] Updated: (LUCENE-1249) Bugs in
org.apache.lucene.index.TermVectorsReader.clone()
[ https://issues.apache.org/jira/browse/LUCENE-1249?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Busch updated LUCENE-1249:
----------------------------------
Fix Version/s: (was: 2.3.2)
2.4
> Bugs in org.apache.lucene.index.TermVectorsReader.clone()
> ---------------------------------------------------------
>
> Key: LUCENE-1249
> URL: https://issues.apache.org/jira/browse/LUCENE-1249
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 2.3.1
> Reporter: David Dillard
> Priority: Minor
> Fix For: 2.4
>
>
> A couple of things:
> - The implementation can return null which is not allowed. It should throw a CloneNotSupportedException if that's the case.
> - Part of the code reads:
> TermVectorsReader clone = null;
> try {
> clone = (TermVectorsReader) super.clone();
> } catch (CloneNotSupportedException e) {}
> clone.tvx = (IndexInput) tvx.clone();
> If a CloneNotSupportedException is caught then "clone" will be null and the assignment to clone.tvx will fail with a null pointer exception.
