Ian updated GROOVY-9570:
------------------------
    Description: 
 

 
{code:java}
import groovy.transform.TypeChecked

@TypeChecked
abstract class A<T extends List>{
    Collection<T> testQueue
    Closure c = {
        testQueue.each{T item->
            println item
        }
    }
    //def foo() {
    //    testQueue.each{T item->
    //        println item
    //    }
    //}
}
new A<LinkedList>(){}
{code}
Put this in filename.groovy and call "groovy filename.groovy" and I get

 
{noformat}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/ianl/closureGeneric.groovy: 9: Expected parameter of type 
java.lang.Object but got T
 @ line 7, column 24.
           testQueue.each{T item->
                          ^
1 error{noformat}
Yet, uncomment the method foo() and there's no error there. or put the closure 
definition into the method and there's no error.
