Julian Reschke commented on JCR-3082:
-------------------------------------
This seems to be caused by
@Override
public int nextDoc() throws IOException {
while (currentDoc != NO_MORE_DOCS) {
if (scorers[currentScorer].nextDoc() != NO_MORE_DOCS) {
currentDoc = scorers[currentScorer].docID() +
starts[currentScorer];
return currentDoc;
} else if (++currentScorer < scorers.length) {
// advance to next scorer
} else {
// no more scorers
currentDoc = NO_MORE_DOCS;
}
}
return currentDoc;
}
which allows currentScorer to go beyond scorers.length and
@Override
public float score() throws IOException {
return scorers[currentScorer].score();
}
which assumes it is in-range.
Not sure whether the caller is supposed to call score() when the object is in
this state.
Changing it to
@Override
public int nextDoc() throws IOException {
while (currentDoc != NO_MORE_DOCS) {
if (scorers[currentScorer].nextDoc() != NO_MORE_DOCS) {
currentDoc = scorers[currentScorer].docID() +
starts[currentScorer];
return currentDoc;
} else if (currentScorer + 1 < scorers.length) {
// advance to next scorer
currentScorer += 1;
} else {
// no more scorers
currentDoc = NO_MORE_DOCS;
}
}
return currentDoc;
}
fixes the runtime exception, but I'm not totally sure about the correctness.
