Issue with Java 7.51 update for Licensed CF 10 applications

We have Licensed ColdFusion 10 Enterprise applications on our server .When Java client is upgraded to Java 7.51, we are getting following error while working with our functionality.

"missing required permissions manifest attribute in main jar"

This problem is occurring when we use cftree. we try to find solutions for this but didnt got any break through. When checked on Java site we see that this error occurs if the applets are not signed or self signed.
