[9] Review request: JDK-8169443 Deprecate Java Packager Blob Signing

[Stefan Fuchs]

Well, in Java 8 <fx:signjar> is part of the javafx_ant_task reference [1]
and advertised as being the new and more efficient way to sign jars [2]

Anyway, perhaps the deprecation message for <fx:signjar> could be 
enhanced to point to https://ant.apache.org/manual/Tasks/signjar.html as 
the recommended way to sign jars.
The Deployment Guide should be updated as well.
