You can either check out the entire current trunk source code and build that,
or download the release source and libs, apply the patch, and build that.
Which do you want to do?

It's a bug in the code.
Whenever the JDBC connector rejects a document based on what the downstream
pipeline tells it to do, it improperly accounts for that and you get this
error. The fix is quite simple and I can attach a patch, and will do so
shortly. Thanks!

Hi,
The proximate cause of the problem is that there are multiple "resolutions"
occurring for one document in the JDBC crawl set. When a connector is asked to
process a document, it must tell the framework what is to be done with it --
either it gets indexed, or it gets skipped, or it gets deleted. The problem is
that the connector is telling the framework TWO things for the same document.
The code in question:
{code}
// Now, go through the original id's, and see which ones are still in the
map. These
// did not appear in the result and are presumed to be gone from the
database, and thus must be deleted.
for (final String documentIdentifier : fetchDocuments)
{
if (!seenDocuments.contains(documentIdentifier))
{
// Never saw it in the fetch attempt
activities.deleteDocument(documentIdentifier);
}
else
{
// Saw it in the fetch attempt, and we might have fetched it
final String documentVersion = map.get(documentIdentifier);
if (documentVersion != null)
{
// This means we did not see it (or data for it) in the result set.
Delete it!
activities.noDocument(documentIdentifier,documentVersion);
{code}
It's failing on the last line. The connector thinks there is in fact no
document that exists (based on the version query you gave it), BUT based on the
results of the other queries, it thinks the document does exist (and was in
fact processed).
I will need to look carefully at the queries and at the connector code to
figure out exactly how that can happen, and then I can let you know whether
it's a bug in the code or a bug in your queries. Stay tuned.
