Subject [jira] Created: (LUCENE-1604) Stop creating huge arrays to represent the absense of field norms

Stop creating huge arrays to represent the absense of field norms
-----------------------------------------------------------------

                 Key: LUCENE-1604
                 URL: https://issues.apache.org/jira/browse/LUCENE-1604
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
    Affects Versions: 2.9
            Reporter: Shon Vella
            Priority: Minor


Creating and keeping around huge arrays that hold a constant value is very inefficient both
from a heap usage standpoint and from a localility of reference standpoint. It would be much
more efficient to use null to represent a missing norms table.
