Title:
  SparkAngels cannot connect to its servers :
  java.security.AccessControlException: access denied
  (java.lang.RuntimePermission
  accessClassInPackage.sun.security.internal.spec)

Status in “openjdk-6” package in Ubuntu:
  New

Bug description:
  SparkAngels is a java application that is runned via JNLP. http://www.spark-angels.com
  The current jnlp file can be found here : http://dnld0.sparkom.com/sparkangels/sangels/sparkangels.jnlp

  
  With OpenJDK 6b20-1.9.10-0ubuntu1~10.04.2, it starts OK, but fails to connect to its servers.

  To reproduce, you can start the JNLP on command-line (javaws sparkangels.jnlp), open the dropdown "Options", choose "Utilisation par code" then "Obtenir un code" (this is in French, maybe it would be translated in your language when you run it)
  At this moment, the application tries to connect to its servers and it fails with the following error message in the log :
  ---W-A-R-N-I-N-G--- IO-ERROR CONTACTING SERVER cccp1.sparkom.com: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.security.internal.spec)
  ---W-A-R-N-I-N-G--- IO-ERROR CONTACTING SERVER cccp0.sparkom.com: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.security.internal.spec)
  sparkangels.xu: No server available

  	at sparkangels.q.b(Unknown Source)
  	at sparkangels.ih.run(Unknown Source)
  ---W-A-R-N-I-N-G--- EXCEPTION MESSAGE: No server available

  If I use sun-java-6 packages instead of openjdk-6, it works correctly.
  If I try to open the same jnlp with oneiric (with version 6b23~pre11-0ubuntu1.11.10), it works correctly.

  So it looks like a bug on this version of openjdk, that has been fixed in latest ubuntu version.
  I found a workaround here : https://bugzilla.redhat.com/show_bug.cgi?id=471413#c33
  You simply have to create a file ~/.java.policy with this content :
  grant {
     permission java.security.SecurityPermission 
          "putProviderProperty.SunJCE";
     permission java.lang.RuntimePermission
          "accessClassInPackage.sun.security.internal.spec";
     permission java.lang.RuntimePermission
         "accessClassInPackage.sun.security.rsa";
     permission java.lang.RuntimePermission
          "accessClassInPackage.sun.security.internal.interfaces";
  };

  
  This application is very usefull to provide assistance through a remote desktop access. It's an alternative to VNC when NAT/port-forwarding is not properly configured.
  Ideally, a backport would
  A similar problem seems to happen on other java applications : http://www.havenandhearth.com/forum/viewtopic.php?f=4&t=15576
