[patch] bad field masking makes non functional rowsInput evaluation
-------------------------------------------------------------------

                 Key: DERBY-5034
                 URL: https://issues.apache.org/jira/browse/DERBY-5034
             Project: Derby
          Issue Type: Bug
          Components: Network Server
    Affects Versions: 10.7.1.1
            Reporter: Dave Brosius
            Priority: Minor
             Fix For: 10.8.0.0
         Attachments: bad_fieldmasking.diff

RealDistinctScalarAggregateStatistics derives from RealScalarAggregateStatistics

RealDistinctScalarAggregateStatistics takes a constructor parm of rowsInput and forwards it
to the super class's constructor, where it is stored for use by the class.

However, the subclass mistakenly added a masked rowsInput field that is never set, and thus
interferes with the proper use of the super class's rowsInput field.


patch removed the erroneous subclass's field.
