Hello All,
I am trying to run a simple viola jones algorithm for detecting human eyes in the images using RapidMiner's Fast Haar Detector operator.
But, unfortunately I'm getting error like,
Exception: java.security.AccessControlException
Message: access denied ("java.lang.RuntimePermission" "modifyThread")
Stack trace:

Could somebody please help me in solving this??
