No, because Java's security hasn't been based on the Security Manager sandbox for years, and very few people use it (and almost no one uses it for sandboxing untrusted code -- what it was designed to do). There will be replacements, and in some cases there are already, for other (ab)uses of the Security Manager, such as tracking I/O events.
