Java 7 Update 51 blocking some access to applications

Neal Soderquist -

Starting with Java 7 Update 51, trying to run Java applications can sometimes generates messages that block access to the application. 

"Java applications are blocked by your security settings"

"Missing Application-Name manifest attribute"

"Missing required permissions manifest attribute in main jar"


Java has provided a work around for this, here. You should only implement this fix if you are sure the application is legitimate.
