In the case as followed: {code:java} ((sal IS NULL) IS NOT NULL) IS FALSE {code} The RexCall#isAlwaysTrue return true,however the correct answer is false. I find the reason is that there is a wrong logic in the isAlwaysTrue,when getKind() is IS_NOT_FALSE、IS_FALSE and IS_NOT_FALSE : !屏幕快照 2018-08-02 下午7.34.26.png!
