[jira] [Updated] (GROOVY-9570) Class-Level Closure Definition With
Generics Fails TypeChecked
[ https://issues.apache.org/jira/browse/GROOVY-9570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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.
