Change of the toString implementation for annotations

[Rafael Winterhalter]

Hello,
I recognized a failing test on Java 9 caused by a changed return value
returned by toString on an annotation with a class-property.

When calling toString on an annotation: @interface Foo { Class<?> value();
} instantiated as @Foo(Bar.class) with Java 8 it would be printed as:

@Foo(class Bar)

while in Java 9 it is printed as:

@Foo(Bar.class)

Is this change intended? I do not see a big benefit of this implementation
change and it could break code. In my case, the problem is not that big, it
is an easy fix but still, I found it a bit surprising.

Thank you.
Best regards, Rafael
