Deprecated container annotations

[Alex Buckley]

Hi Jesper,

You are correct:

- By JLS8 9.6, Foo is a legal repeatable annotation type, and 
FooContainer is a legal containing annotation type of Foo, so the Java 
language has no warnings or errors for the declarations of Foo and 
FooContainer.

- By JLS8 9.6.3.6, the deprecated type FooContainer is used in the 
container annotation @FooContainer which is implicitly declared at the 
site of @Foo @Foo. So, a deprecation warning is due at @Foo @Foo. A note 
in 9.6.3.6 identifies the possibility of an "invisible" container 
annotation causing a warning.
