This is usual code:
@Autowire
private Service service;
But with Java 7 this also works (and shorter):
private @Autowire Service service;
Is that legal in Java 8 (have same semantic)? Is that bad coding practice?

Protected Access Modifier - Protected Variables, methods, and constructors, which are declared protected in a superclass can be accessed only by the subclasses in other package or any class within the package of the protected members' class. The protected access modifier cannot be applied to class and interfaces.
The 3 values that the @Retention annotation can have: SOURCE: Annotations will be retained at the source level and ignored by the compiler. CLASS: Annotations will be retained at compile-time and ignored by the JVM. RUNTIME: These will be retained at runtime.
Private. Any method, property or constructor with the private keyword is accessible from the same class only. This is the most restrictive access modifier and is core to the concept of encapsulation.
There isn't a friendly modifier in Java. In Java it is called package private. And it is the default modifier.
According to documentation
In Java 7 :
Annotations can be applied to declarations: declarations of classes, fields, methods, and other program elements. When used on a declaration, each annotation often appears, by convention, on its own line.
As of the Java SE 8 release, annotations can also be applied to the use of types. :
Class instance creation expression:
new @Interned MyObject();
Type cast:
myString = (@NonNull String) str;
implements clause:
class UnmodifiableList<T> implements
@Readonly List<@Readonly T> { ... }
Thrown exception declaration:
void monitorTemperature() throws
@Critical TemperatureException { ... }
