Incorrect rewrite of not disjunctive criteria
----------------------------------------------
Key: TEIID-1498
URL: https://issues.jboss.org/browse/TEIID-1498
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.
