["Alexandre Boudnik (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-3389?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexandre Boudnik updated IGNITE-3389:
--------------------------------------
    Description: 
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}
