java - 添加到 X509Data 的证书列表时 X509Certificates 重复

Question

我正在尝试将证书添加到 OpenSAML 中的 X509Data 对象。然而，当我这样做时，证书似乎被添加了两次。下面的代码演示了这一点。我是不是做了什么蠢事？

import org.junit.Test;
import org.opensaml.Configuration;
import org.opensaml.DefaultBootstrap;
import org.opensaml.xml.ConfigurationException;
import org.opensaml.xml.XMLObjectBuilderFactory;
import org.opensaml.xml.signature.X509Certificate;
import org.opensaml.xml.signature.X509Data;

import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.assertThat;


public class BrokenListAdditionTest {
    @Test
    public void shouldNotFail() throws ConfigurationException {
        DefaultBootstrap.bootstrap();

        XMLObjectBuilderFactory openSamlBuilderFactory = Configuration.getBuilderFactory();
        X509Certificate x509Certificate = (X509Certificate) openSamlBuilderFactory.getBuilder(X509Certificate.DEFAULT_ELEMENT_NAME).buildObject(X509Certificate.DEFAULT_ELEMENT_NAME, X509Certificate.DEFAULT_ELEMENT_NAME);
        x509Certificate.setValue("foo-value");
        X509Data x509Data = (X509Data) openSamlBuilderFactory.getBuilder(X509Data.DEFAULT_ELEMENT_NAME).buildObject(X509Data.DEFAULT_ELEMENT_NAME, X509Data.TYPE_NAME);
        x509Data.getX509Certificates().add(x509Certificate);

        assertThat(x509Data.getX509Certificates().size(), is(1)); // Fails, because size() is 2!?
    }
}

这很奇怪，我还没有找到很好的解释。正如我在评论中所说，似乎正在完成某种索引。

但是，我尝试将元素编码到 XML 中，一切看起来都很好。所以我认为你无论如何都可以使用它。

<?xml version="1.0" encoding="UTF-8"?>
<ds:X509Data xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="ds:X509DataType">
<ds:X509Certificate xsi:type="ds:X509Certificate">foo-value</ds:X509Certificate>
</ds:X509Data>
