OK - There is a workaround: The DRAC5 systems must be added to the "Exception Site List" (This can be done in the Java Control Panel in the "Security" section). Nevertheless it would be nice if Dell would fix this in any upcoming firmware release.
Hi Everybody! After the usual Java update (to Java 7 Update 51) the remote console does not start any more. The java application launcher shows a "Unable to launch application"-Error. Here some more details: DRAC Firmware Version: 1.65 (12.08.16) java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: [URL]  at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source) at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source) at com.sun.javaws.Launcher.doLaunchApp(Unknown Source) at com.sun.javaws.Launcher.run(Unknown Source) at java.lang.Thread.run(Thread.java:744) I hope that Dell will provide a fix ASAP.
