Java nullable annotation doesn't compile when applied to fully qualified names

[msjarrett]

--java-nullable-annotation org.checkerframework.checker.nullness.qual.Nullable

If an interface uses a type from a different Java package (using @extern foo.yaml), the output will be @annotation fully.qualified.ClassName, which causes Java compilation problems.

For example:
public abstract io.grpc.Status send(Id recipient, @nullable com.google.package.Message message);

Results in:
error: scoping construct cannot be annotated with type-use annotation: @org.checkerframework.checker.nullness.qual.Nullable

Not a Java expert, but I think the correct way to apply the annotation is:
com.google.package.@nullable Message
