------------------------------------------

             Summary: Declared generic parameter on method not transferred to Closure
                 Key: GROOVY-10792
                 URL: https://issues.apache.org/jira/browse/GROOVY-10792
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 4.0.6
            Reporter: Christopher Smith


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}
