Hi Rafa,
In that case, I think you are passing in a document identifier that is not
one that was given to you by the processDocuments() invocation.
Essentially, there's a hash table and it's trying to look up the
corresponding record, and it's null.
You can confirm this by modifying line 2147 of WorkerThread, which reads:
return new
PipelineSpecificationWithVersions(pipelineSpecification,previousDocuments.get(documentIdentifierHash),componentIdentifierHash);
... adding in debugging code to throw an IllegalArgumentException when
previousDocuments.get(documentIdentifierHash) is null:
if (previousDocuments.get(documentIdentifierHash) == null)
throw new IllegalArgumentException("Unrecognized document identifier");
