Key: GROOVY-11121
URL: https://issues.apache.org/jira/browse/GROOVY-11121
Project: Groovy
Issue Type: Bug
Components: Static Type Checker
Reporter: Thodoris Sotiropoulos
I have the following program
{code}
import java.util.function.*;
class Foo<T> {
static <T> Foo<T> of(Iterable<T> values) { return null; }
static <T> Foo<T> of(T values) { return null; }
}
class Main {
static final void test() {
Foo.<IntUnaryOperator>of((int s) -> s + 1);
}
}
{code}
h3. Actual behavior
{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 10: [Static type checking] - Wrong number of parameters for method
target: iterator()
@ line 10, column 38.
var x = Foo.<IntUnaryOperator>of((int s) -> s + 1);
^
1 error
{code}
h3. Expected behavior
Compile successfully
h3. Notes
Test case adapted from the following program that uses the apache-commons-io
library:
{code}
import org.apache.commons.io.function.*;
import java.util.function.*;
class Main {
static final void test() {
var x = IOStream.<IntUnaryOperator>of((int s) -> s + 1);
}
}
{code}
