---------------------------------------
Summary: Cannot use closures as arguments for varargs method
Key: GROOVY-10529
URL: https://issues.apache.org/jira/browse/GROOVY-10529
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 3.0.10
Environment: Edition Windows 10 Enterprise
Version 20H2
Installed on 10/12/2020
OS build 19042.685
Experience Windows Feature Experience Pack 120.2212.551.0
Reporter: Kevin Sheppard
When I run the following code:
{code:groovy}
interface Handler {
void handle(String)
}
def foo(Handler... handlers) {
handlers.each { it.handle('Hello!') }
}
foo({ print(it) }, { print(it.toUpperCase()) }) {code}
I get this error message:
{noformat}
No signature of method: ConsoleScript8.foo() is applicable for argument types:
(ConsoleScript8$_run_closure1, ConsoleScript8$_run_closure2) values:
[ConsoleScript8$_run_closure1@4359df7, ConsoleScript8$_run_closure2@4288c46b]
{noformat}
Apparently, Groovy isn't seeing the closures as instances of Handler. This
doesn't happen in Java or Kotlin.
