XML parsing fails with jetty 10

[smitagarg1]

old Jetty version used : 9.4.43.v20210629 New Jetty version : 10.0.12

I have Junit test written where below is returned as mock response and then parsed using org.eclipse.jetty.xml.XmlParser

org.apache.http.HttpEntity responseEntity = new org.apache.http.entity.StringEntity(
              "\<VarrayCapacityDetail>\n" +
                    "\<Varray>\n" +
                        "\<VarrayId>\n" +
                            "urn:storageos:***:a19*******4f\n" +
                        "\</VarrayId>\n" +
                        "\<TotalCapacity>3</TotalCapacity>\n" +
                        "\<UsedCapacity>2</UsedCapacity>\n" +
                    "\</Varray>\n" +
                "\</VarrayCapacityDetail>");
				
				
when(response.getEntity()).thenReturn(responseEntity);				
InputStream stream = response.getEntity().getContent();				
XmlParser.Node VArrayCapacitynode=null;
				try {
					VArrayCapacitynode = xmlParser.parse(stream);
				} catch (SAXException e) {
					e.printStackTrace();
					_log.error("Error Occured in parsing the varray Capacity xml", e);
			}

This works fine with jetty 9.4.43.v20210629 but fails with jetty 10.0.12 and gives below error

com.emc.storageos.data.ssmclientapp.util.DtQueryUtilTest > testGetVarray_success STANDARD_ERROR

Your XML is badly formed as the TotalCapacity and UsedCapacity elements are not closed. You also may need to turn off validation.

I fixed the XML and wrote the following, which works fine:

    @Test
    public void testIssue() throws Exception
    {
        XmlParser parser = new XmlParser();
        parser.setValidating(false);

        XmlParser.Node parsed = parser.parse(
            new ByteArrayInputStream((
                "<VarrayCapacityDetail>\n" +
                "<Varray>\n" +
                "  <VarrayId>\n" +
                "    urn:storageos::a19****4f\n" +
                "  </VarrayId>\n" +
                "  <TotalCapacity>3</TotalCapacity>\n" +
                "  <UsedCapacity>2</UsedCapacity>\n" +
                "</Varray>\n" +
                "</VarrayCapacityDetail>").getBytes(StandardCharsets.ISO_8859_1)));
        System.err.println(parsed);
    }

This issue has been automatically marked as stale because it has been a full year without activity. It will be closed if no further activity occurs. Thank you for your contributions.

Closing, it works when you turn off validation.
