Getting the following exception when trying to launch the Ignition project:

java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: [spark:8088/main/system/launchbin … client.jar](http://spark:8088/main/system/launchbin/launchclient.jar)  
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(Unknown Source)

Here’s the launch file:

 Resource Prowess: Right Person, Right Project Inductive Automation 

I have the following Java version: Version 7 Update 51

What to do to correct this issue?
