Get ExtensionValue from x509Certificate
<p>I use bouncycastle in Java</p>

<pre><code>CertificateFactory.getInstance("X509", "BC")
certFactory.generateCertificate(in)
</code></pre>

<p>to generate the cert. It works fine. But when I use </p>

<pre><code>x509Certificate.getExtensionValue("1.2.3.4.5.6.7")
</code></pre>

<p>The return value does not match the membersrvc's one.
Did I miss some thing?</p>
