该服务器的证书链不完整。使用openssl将等级限制为B，但不使用jdk

Question

使用openssl时，在ssl测试中提示“此服务器的证书链不完整。等级限制为B”。但是，使用jdkssl时，获得了完整的证书链。

openssl的功能或我的配置不正确吗？

以下是验证客户端代码。

SSLContext context = SSLContext.getInstance("TLS");
    X509TrustManager x509m = new X509TrustManager() {

        @Override
        public X509Certificate[] getAcceptedIssuers() {
            System.out.println("getAcceptedIssuers......");
            return null;
        }

        @Override
        public void checkServerTrusted(X509Certificate[] chain, String authType)
                throws CertificateException {
            System.out.println("checkServerTrusted......");
            //When I use jdkssl the chain'value is all of my server configured.
            //But when openssl the chain'value only one
            //Why this happened? is my server configuration incorrect or this is openssl's feature?
        }

        @Override
        public void checkClientTrusted(X509Certificate[] chain, String authType)
                throws CertificateException {
            System.out.println("checkClientTrusted......");

        }
    };
    context.init(null, new TrustManager[] { x509m }, new SecureRandom());
