Public bug reported:
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--- 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 :
