我正在尝试将证书文件加载到证书对象中，但出现以下异常。
java.security.cert.CertificateParsingException: invalid DER-encoded certificate data
at sun.security.x509.X509CertImpl.parse(X509CertImpl.java:1701)
at sun.security.x509.X509CertImpl.<init>(X509CertImpl.java:303)
at sun.security.provider.X509Factory.parseX509orPKCS7Cert(X509Factory.java:532)
at sun.security.provider.X509Factory.engineGenerateCertificates(X509Factory.java:417)
at java.security.cert.CertificateFactory.generateCertificates(CertificateFactory.java:427)
下面是我用来读取证书文件的代码，
final CertificateFactory certFactory = CertificateFactory.getInstance("X.509");
final Collection<? extends Certificate> certs =
(Collection<? extends Certificate>) certFactory.generateCertificates(new ByteArrayInputStream(FileUtils.readFileToByteArray(serverCertFile)));
以下是证书文件的内容，

如果我使用相同的代码从顶部删除证书文件中的内容直到开始证书，它工作正常。但我的要求是证书文件将包含这些内容。有人遇到过这个错误吗？任何帮助将不胜感激。
