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: 2.3.2
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.
