exception:java.security.cert.CertificateException:没有可用的X509TrustManager实现

Question

    //Load Two Keystores
    KeyStore keystore = KeyStore.getInstance("pkcs12", "SunJSSE");
    InputStream keystoreInput = new FileInputStream(cerPath);
    keystore.load(keystoreInput, passwd.toCharArray());
    System.out.println("Keystore has " + keystore.size() + " keys");

    // load the truststore, leave it null to rely on cacerts distributed with the JVM
    KeyStore truststore = KeyStore.getInstance("pkcs12", "SunJSSE");
    InputStream truststoreInput = new FileInputStream(cerPath);
    truststore.load(truststoreInput, passwd.toCharArray());
    System.out.println("Truststore has " + truststore.size() + " keys");

    //ssl context
    SSLContext sslcontext = SSLContext.getInstance("TLS");
    sslcontext.init(null, null, null);
    SSLSocketFactory sf = new SSLSocketFactory(keystore, passwd);
    Scheme https = new Scheme("https", 443, sf);

    SchemeRegistry schemeRegistry = new SchemeRegistry();
    schemeRegistry.register(https);
    ...
    client = new DefaultHttpClient(new PoolingClientConnectionManager(schemeRegistry));
    ...
    HttpResponse httpResponse = client.execute( targetHost, httpMethod);

javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No X509TrustManager implementation available

普通的SSL属性（）也不起作用。

最后我们发现了问题。

我们在pom.xml中有一个指向框架wiremock的依赖项：

     <dependency>
        <groupId>com.github.tomakehurst</groupId>
        <artifactId>wiremock</artifactId>
        <version>1.43</version>
        <exclusions>
             <exclusion>
              <groupId>org.mortbay.jetty</groupId>
              <artifactId>servlet-api</artifactId>
            </exclusion>
         </exclusions> 
    </dependency>

这个框架在jar中包含一个/keystore文件，该文件产生了这个问题。当我们从pom中移除这个依赖项时，所有工作都很好。
