  30  * Exception joining all the problems that {@link AdvancedX509TrustManager} can find in
  31  * a certificate chain for a server.
  32  *
  33  * This was initially created as an extension of CertificateException, but some
  34  * implementations of the SSL socket layer in existing devices are REPLACING the CertificateException
  35  * instances thrown by {@link javax.net.ssl.X509TrustManager#checkServerTrusted(X509Certificate[], String)}
  36  * with SSLPeerUnverifiedException FORGETTING THE CAUSING EXCEPTION instead of wrapping it.
  37  *
  38  * Due to this, extending RuntimeException is necessary to get that the CertificateCombinedException
  39  * instance reaches {@link AdvancedSslSocketFactory#verifyPeerIdentity}.
  40  *
  41  * BE CAREFUL. As a RuntimeException extensions, Java compilers do not require to handle it
  42  * in client methods. Be sure to use it only when you know exactly where it will go.
