Description

IndexingFiltersChecker may throw null pointer exceptions if

1. content returned by protocol implementation is null (artifact of NUTCH-1293)
2. if one of the indexing filters sets doc to null (the interface IndexingFilter allows to exclude documents by returning null, cf. the IndexingFilter of NUTCH-966)
