[jira] [Updated] (CALCITE-2669) RelMdTableReferences should check whether references inferred from input are null for Union/Join operators

     [ https://issues.apache.org/jira/browse/CALCITE-2669?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jesus Camacho Rodriguez updated CALCITE-2669:
---------------------------------------------
    Description: 
Currently, there is no check and we iterate directly over the set returned, which may lead to a NPE if there is an operator underneath that is not supported.
