>          Issue Type: Improvement
>    Affects Versions: 3.1
>            Reporter: Dmitri Blinov

> It is expected that the following code
> {code:java}
> @Annotation while (true) {}
> {code}
> should be successfully parsed as the code below
> {code:java}
> @Annotation {while (true) {}}
> {code}
> The suggestion is to change the grammar for the annotated statement from
> {code:java}
> void AnnotatedStatement() #AnnotatedStatement() : {}
>  {
>     (LOOKAHEAD(<ANNOTATION>) Annotation())+ (LOOKAHEAD(<VAR>) Var() | LOOKAHEAD(1) Block() | Expression())
>  }
> {code}
> to
> {code:java}
> void AnnotatedStatement() #AnnotatedStatement() : {}
>  {
>     (LOOKAHEAD(<ANNOTATION>) Annotation())+ (LOOKAHEAD(1) Block() | Statement())
>  }
> {code}
