-----------------------------------

             Summary: Drill JDBC driver emits reflective access warnings under 
Java 9+
                 Key: DRILL-8497
                 URL: https://issues.apache.org/jira/browse/DRILL-8497
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.21.1
            Reporter: James Turton
            Assignee: James Turton


The failed code patching appears inconsequential to the JDBC driver's 
functioning but results in log noise for applications. Example warning
{code:java}
