I have java version "1.7.0_25". And i tried what has been suggested
sudo /usr/libexec/PlistBuddy -c "Delete :JavaWebComponentVersionMinimum" /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist
However my conference launch still fails with the following error :
ExitException[ 3]java.lang.SecurityException: Bad package name of main-class
at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
at com.sun.javaws.Launcher.run(Unknown Source)
Appreciate any help..
