Teiid查询联接计划无限循环

Question

执行以下SQL时，我们遇到无限循环：

SELECT c._COMPTE,
       u.CalculatedField,
       cl.CHAMPSFCP__VALEUR,
       ch_41.CH41__VALEUR,
       ch_5.CH5__VALEUR
  FROM OmgModel_Z1rP.OMG.dbo.CPARTFCP c
  LEFT JOIN BInv6BusinessModel.FREPACCOUNTUNION u
    ON u.FREP_AFAINB = c._USERNAME
   AND u.CalculatedField6 = 'B'
  LEFT JOIN BInv6BusinessModel.ClientTypeCode cl
    ON c._COMPTE = cl.CHAMPSFCP__COMPTE
  LEFT JOIN (SELECT ch._COMPTE AS CH41__COMPTE,
                    ch._VALEUR AS CH41__VALEUR
               FROM OmgModel_Z1rP.OMG.dbo.CHAMPSFCP ch
              WHERE ch._NUMCHAMPS = 41) ch_41
    ON c._COMPTE = ch_41.CH41__COMPTE
  LEFT JOIN (SELECT ch._COMPTE AS CH5__COMPTE,
                    ch._VALEUR AS CH5__VALEUR
               FROM OmgModel_Z1rP.OMG.dbo.CHAMPSFCP ch
              WHERE ch._NUMCHAMPS = 5) ch_5
    ON c._COMPTE = ch_5.CH5__COMPTE LIMIT 0, 10

调试后，发现问题出在类RulePlanOuterJoins方法planLeftOuterJoinAssociativityBeforePlanning。

问题来自下面的代码行，如果已删除，则不会重现该问题：

changedAny |= val;
