Java annotation declaration being handled correctly

[SamMaier]

Summary

Previously, Java annotation declarations (@interface AnnotationName) were being handled as ObjC interfaces. This caused the brace formatting to mess up, so that when you had a class with an interface defined in it, it would indent the final brace of the class.

It used to format this class like so:

class A {
  @interface B {}
  }

But will now just skip the @interface and format it like so:

class A {
  @interface B {}
}

Thanks for the fix! Do you happen to know what had regressed this?
