I am hitting the below exception when using Connection.prepareStatement without binding any parameters

PreparedStatement stmt = con.prepareStatement(DRILL_SAMPLE_QUERY);

Exception in thread "main" java.lang.ClassCastException: org.apache.drill.jdbc.impl.DrillJdbc41Factory$DrillJdbc41PreparedStatement cannot be cast to org.apache.drill.jdbc.impl.DrillStatementImpl
