> Need to handle when ResultSet has no cursor. It happened only with client JDBC. This
code throws NPE:
> {code}
>     public void testMetadataResultSetClose() throws Exception {
>         try (Connection conn = DriverManager.getConnection(BASE_URL)) {
>             try (ResultSet tables = conn.getMetaData().getTables(null, null, "%", null))
{
>                 int columnCount = tables.getMetaData().getColumnCount();
>                 while (tables.next())
>                     for (int i = 0; i < columnCount; i++)
>                         tables.getObject(i + 1);
>             }
>         }
>     }
> {code}
