> Issue Type: Bug
> Components: Compiler, groovy-runtime
> Affects Versions: 3.0.9
> Reporter: Arthur Sengileyev

> Closure passed to field annotation fails to find static method of the same
> class if Compiled to dynamic code.
>
> Code example, which shows how the same code works for statically compiled
> class, but fails for precise copy compiled dynamically.
