> This is probably a duplicate, but I'm not sure which of.
> I'm using Awaitility's {{until(Callable<Boolean>)}} and passing it a closure:
> {code:groovy}
> List<String> buffer = []
> ...
> await().until { buffer }
> {code}
> Expected behavior: {{buffer}} is coerced to a boolean using Groovy truth.
> Actual behavior: 
> {code}
> java.lang.ClassCastException: class java.util.ArrayList cannot be cast to class java.lang.Boolean
> {code}
