> When listing multiple scoring filters in certain properties (listed below) in "nutch-site.xml", it is vital that no spaces/newlines/tabs are placed in front of the value content.
> E.g.:
> This is fine:
> <value>org.apache.nutch.scoring.opic.OPICScoringFilter myFilter</value>
> Either of these will generate an exception:
> <value> org.apache.nutch.scoring.opic.OPICScoringFilter myFilter</value>
> <value>
> org.apache.nutch.scoring.opic.OPICScoringFilter
> myFilter
> </value>
> Affects these properties in "nutch-site.xml":
> * indexingfilter.order
> * urlnormalizer.order
> * urlfilter.order
> * htmlparsefilter.order
> * scoring.filter.order
> Solution: replaced {order.split("\\s+")} to {order.trim().split("\\s+")}. Patch provided.
