title: keyStore.load(null,null) hangs
body: <p>I was trying load <code>keystore</code> from <code>smartCard</code>. I have a valid <code>smartcard</code> with self signed cert.</p>
  
  <pre><code>KeyStore keyStore = KeyStore.getInstance("Windows-MY")
  keyStore.load(null,null);
  </code></pre>
  
  <p>It hangs up on <code>KeyStore.loadKeysorCertificateChains(String,Collection&lt;KeyEntry&gt;)</code> with no response back. I am wondering what the problem could be.</p>
  
  <p>Should I add root cert into <code>CERT</code> keys or am I missing something else?</p>
