Michael McCandless commented on LUCENE-3377:
--------------------------------------------
I think we should record which IR instance the DTO.TermOrdsIterator was created on, and then don't reuse the passed instance if it came from a different IR?
Actually we should probably just hold onto & compare the IR.getCoreCacheKey().

Martijn van Groningen updated LUCENE-3377:
------------------------------------------
Description:
TermOrdsIterator's lookup method can throw an ArrayIndexOutOfBoundsException if reuse argument is reused acros segments.
Example collector:
{code}
private DocTermOrds.TermOrdsIterator reuse = null;
public void collect(int doc) throws IOException {
...
reuse = docTermOrds.lookup(doc, reuse);
...
}
public void setNextReader(IndexReader.AtomicReaderContext context) throws IOException {
docTermOrds = FieldCache.DEFAULT.getDocTermOrds(context.reader, field);
....
}
{code}
If reuse argument is always null exception doesn't occur.
was:TermOrdsIterator's lookup method thows ArrayIndexOutOfBoundsException if reuse argument is reused acros segments.

bq. Actually we should probably just hold onto & compare the IR.getCoreCacheKey().
Seems like a good idea to me.
