             Summary: Osisoft translator - NPE when running query with LATERAL JOIN
                 Key: TEIID-5136
                 URL: https://issues.jboss.org/browse/TEIID-5136
             Project: Teiid
          Issue Type: Bug
          Components: JDBC Connector
            Reporter: Andrej Šmigala
            Assignee: Steven Hawkins


Running the following query:
{code:sql}
SELECT bqt2.smalla.intkey, g2.intkey, bqt2.smalla.bytenum FROM bqt2.smalla LEFT JOIN LATERAL (SELECT intkey FROM bqt2.mediuma WHERE bqt2.smalla.bytenum = bqt2.mediuma.bytenum) AS g2 ON true
{code}

results in a NPE in teiid (before sending source src command).

Stacktrace:
{noformat}
Connector worker process failed for atomic-request=vEbs99yd+srV.1.0.1: java.lang.NullPointerException
