Incorrect rewrite of not  disjunctive criteria
----------------------------------------------

                 Key: TEIID-1501
                 URL: https://issues.jboss.org/browse/TEIID-1501
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.0
            Reporter: Steven Hawkins
            Assignee: Steven Hawkins
            Priority: Critical
             Fix For: 7.4


The rewrite of a condition such as "not((a or b) AND c)" with a,b,c predicates where c a is predicate that is negatable, such as col1 = 1.  The result should have the negated form of col1 <> 1, but instead has col1 = 1.  This is because the col1 = 1 predicate is repeated in the result, but not cloned and the rewriter modifies the same instance.
