> The patch Nutch-702 implemented the lazy instanciation of CrawlDatum objects,
> but when using the method set(CrawlDatum) to copy the content of an instance
> into the current object we did not reset the metadata of the current object
> if it was null in the instance passed as argument. As a result, the metadata
> of the current object might be kept from a previous CrawlDatum and won't
> correspond to the other fields of the instance.
> The patch attached fixes this issue.
