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--- 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.lt.b(Unknown Source) at sparkangels.vq.a(Unknown Source) at sparkangels.vq.a(Unknown Source) at sparkangels.vq.a(Unknown Source) at sparkangels.q.m(Unknown Source) 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 ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: openjdk-6-jre 6b20-1.9.10-0ubuntu1~10.04.2 ProcVersionSignature: Ubuntu 2.6.38-13.52~lucid1-generic 2.6.38.8 Uname: Linux 2.6.38-13-generic x86_64 Architecture: amd64 CheckboxSubmission: bb64787174aa01f1fb7ecfce8a2f831c CheckboxSystem: 34179ae9d787c87b2b99043345f17cea Date: Thu Dec 1 21:42:28 2011 ExecutablePath: /usr/lib/jvm/java-6-openjdk/jre/bin/javaws.real InstallationMedia: Ubuntu 10.04 LTS "Lucid Lynx" - Release amd64 (20100427.1) ProcEnviron: LANG=fr_FR.utf8 SHELL=/bin/bash SourcePackage: openjdk-6 ** Affects: openjdk-6 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug lucid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/898823 Title: SparkAngels cannot connect to its servers : java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.security.internal.spec) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openjdk-6/+bug/898823/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
