Anurag Shekhar updated DERBY-3456:

    Attachment: derby-3456v4.diff

This patch fixes issues related to unique constraint using 
existing non unique index as backing index (see Army's comments issues 1).

I have updated lterTableConstantAction.java to check for uniqueWithDuplicateNulls while deciding
whether to share existing index or not. In case there is a uniqueWithDuplicateNulls index
it can be used by a non unique index but not vice-versa. 

I am investigating other two issues.
