8006764: FunctionalInterface missing from rt.jar (old build)

[Alan Bateman]

The j.l.FunctionalInterface annotation was added recently but it's not 
showing up in rt.jar when using the old build (NEWBUILD=false). 
Unfortunately we have to keep the old build on life support until the 
new build is bedded down and downstream projects have transitioned.

So I need a reviewer to update FILES_java.gmk to add the class name (in 
the old build then the core area required keeping a list of individual 
classes).

Thanks,

-Alan
